The screw, nuts, and bolt markets have seen a lot of changes in the kinds of products that consumers buy. Over the years, fastener manufacturers have been coming up with unique customized products. Why is this happening? Because they know that consumers have different needs and they want unique screws to fulfill those needs.
Which thread-locking mechanism is ideal for your micro fasteners? Is copper or steel a perfect option for your custom screw options? These are some of the questions that most product assembly technicians ask when looking for fastener options. The global market of micro fasteners is massive, but how can you get the best of what you’re seeking?
This post highlights some of the essential factors that you’ll need to consider when buying micro fasteners for your assembly project. Understanding the primary features of the micro screws that you seek will better and quicken your sourcing process.
For example, custom manufactured micro screws come in different sizes and shapes to meet the various needs of consumers. If you have been looking for the best fastening solutions, you may want to check out the various products that reputable suppliers can offer. But how can you determine whether the supplier is trustworthy or that the products they carry will align with your requirements? Here is a look at some of the factors to consider when looking for the best supplier.
Look For Screws with Washers
When you want to build a custom fastener, you should think of ways to make the screws stronger. One of the best ways of doing so is by using washers. You will notice that although some fasteners come with one washer, others come with several because some machines may need a stronger bond than others. Therefore, before you buy custom screws, ask the supplier about the number of washers that they come with and to what extent they will make your machines stronger.
What’s the Coating Material of Your Micro Screws?
Corrosion quickens the wear of micro fasteners and makes the fastened components loose. But with a proper coating, your micro screws experience less wear and tear. Some linings also make your screws more appealing, and this is ideal for decorative miniature screws.
You may choose to buy chrome-plated or zinc plated screws. Chrome-plated screws have a corrosion-resistant and decorative polished finish. These screws are ideal for components that need high-quality polished finishes. The zinc-plated micro fasteners have improved resistance to corrosion under most environments.
Ask For Screws with Locking Patches
Custom manufactured micro screws are likely to be of better quality when they come with locking pieces. Most manufacturers use nylon threads to coat the external and internal threads. When the coat is applied, it creates a self-locking mechanism on the screws, and this makes them fasten better. Custom fasteners are made using different threads based on the kinds of situations under which they will be used. You may want to talk to the supplier to find out what they can do based on your needs.
Which Material is Ideal for Your Micro Fasteners?
The material that makes up micro screws determines the micro fasteners’ cost, brittleness, strength, and corrosion resistance. Approximately 90% of the micro screws in the market are manufactured from stainless steel. Steel is a preferred material for micro screws because it has a high degree of formability, durability, and strength.
Bronze and brass alloys have considerable corrosion resistance, which makes them ideal for marine engineering. But bronze is expensive, and that is why it’s used in marine works. Aluminum is also a common material used in making corrosion-resistant micro screws. Aluminum is also light-weight and ideal for parts that shouldn’t get heavy.
What’s the Size of Your Preferred Micro Screws?
Screws differ in size, which is a conventional screw differentiating factor for these micro fasteners. Manufacturers of screws make capabilities in specific screw size ranges such as the M5 and smaller or M6 and larger screw sizes.
Inquire About the Screws Suited to Your Size Specifications
Manufacturing screws to the correct value is another crucial factor to consider when buying custom manufactured micro screws. Sometimes, you will notice that fasteners are too small or too big. When they are big, it means that you will have to use a lot of force to fix them. The result is that they will be prone to breakage. On the other hand, screws that are too small are likely to be weak no matter how much you fix them. It is for these reasons that you should talk to the supplier so that they understand the correct values for your needs. The best suppliers have several custom screw options.
What Screw Features Do You Want?
There are many kinds of industrial micro fasteners in the market with diverse applications. For instance, different types of screws may have different heads, sizes, threading, and thread-locking mechanisms. Each type of head and thread-locking method determines the kind of purpose your screw will serve.
As such, you have to choose your micro screws based on their different physical features. You may also opt to customize your micro fasteners to suit your unique needs. Custom screws are ideal when off-the-shelf options can’t fulfill your needs.
Search For a Variety of Plastic Thread Forming Screws
If you want custom manufactured micro screws to have more holding power, you should look for a variety of thread forming screws. You should ensure that you have several fastener options because different types of screws need different types of fastening options. When using the fasteners, you will notice that some of them are easier to drive, but others are not because there is a difference in the size of threads. It is good to ask the suppliers for narrow or broader threads based on what you want to do with the fasteners.
What's Your Micro Fastener Source?
You can source your tiny screws from a screw manufacturer or a screw distributor. The latter is often the preferred option when looking for diversified types of screws and large volume orders. But when looking for a wider variety of fasteners in the low volume range, then it is advisable to buy from a distributor.
Unlike manufacturers who may fail to give quotes on small volumes of micro screws, your distributor can provide quotes for any quantity of screws. Sourcing from a distributor is also beneficial when you’re looking for screws from different manufacturers.
Identify the Best Manufacturers and Suppliers
Identifying the right screw supplier involves looking at the kinds of customers that use their services. For instance, the best manufacturers are those that have a broad customer base. If they are supplying to some of the largest custom manufacturers, you can count on them to provide enough screws. Imagine a situation where you need 100 piece packages of screws. In such a case, you will be looking for suppliers with the capacity to deliver large quantities.
More than 200 billion fasteners are used in the U.S. each year. from technological to construction-based industries, that’s a lot of demand. Screws are responsible for holding your product or project together.
The electronics industry has always been driven by innovation. Whether a company is involved in creating consumer electronics, medical devices, small toys, miniaturized robots, circuits board assemblies, or electrical components, they all invest heavily in the research and development of new products. With constant pressure on company engineering teams to create new, and improve existing products, more quickly and more cheaply, many electronics companies are using analytics to gain insights into improving their manufacturing processes. In addition, a growing number of companies in the electronics industry are outsourcing the manufacturing of their parts or even their products, so they can concentrate instead on developing strategies to remain competitive in the global marketplace.
Another factor of cost-control, often overlooked in manufacturing cost-analysis, is the importance of specifying the correct fasteners in the conceptual and research phases of product design. Not using the best type or size of fastener can have a major impact on production costs and the ultimate success of the product in the marketplace.
The cost of making small electronic screw changes during the production cycle can be significant. However, making the right fastener decisions, such as specifying custom-designed small screws for electronics, early in the product’s design phase, can lower production and assembly costs by reducing the component’s per-piece price or eliminating manual operations. To assure that you can offer new products of maximum quality at the lowest cost, take advantage of the input of top design engineers, like the experts at Screw, to customize fasteners to your specific needs during design and development. The right fasteners can prevent costly failures and delays in production, and increase your ability to offer high-quality products at the lowest cost.
When considering a redesign, such as switching to a more durable material for a frequently impacted small component, you’ll want to consult a micro screw specialist to customize fastener compatible with the new material. If this element of the redesign is overlooked, the consequences could be very costly – with products being returned for repairs, lower customer satisfaction, higher warranty costs, or even a recall of the product.

The team at Screw works diligently to provide unparalleled solutions to meet the electronics industry need for micro fasteners by creating custom machine screws with the highest level of integrity for their product or assembly.
Finding a screw manufacturer that can produce high quality items is absolutely key — don’t take a risk on a cheap price and a cheap product. If you rely on custom fasteners, you’ve got a lot of options in terms of handpicking your own manufacturer. Selecting the right one can mean the difference between a product that withstands the test of time, or one that crumples at the first sign of stress; here are the most important characteristics you should look for in a custom screw manufacturer.

Did you know that it wasn’t until 1928 that the National Screw Thread Commission established a standard for screw threads? Before that, all screws needed to be handmade, so no two were ever alike. While those methods are obviously long gone, sometimes — especially in the case of extremely low-cost fasteners — inconsistencies exist. As a business owner, you can’t afford to have some products that stay together and some that fall apart. Look into your screw manufacturer’s previous clients’ experiences to see if they’ve had any similar issues.
Surface treatment is a process method, which refers to the artificial formation of a surface layer on the surface of the substrate material with different mechanical, physical, and chemical properties from the substrate. The purpose of surface treatment is to meet the requirements of product wear resistance, corrosion resistance, decoration, and so on.
In the selection of screws, in addition to the main consideration, the color of the appearance and corrosion resistance should also be considered. Common surface treatment processes for screws include oxidation, electrophoresis, electroplating, dacromet, and so on.
Black Oxidation Treatment
Black oxidation treatment is a common method of chemical surface treatment, the purpose is to produce an oxide film on the metal surface to isolate the air and prevent rust.
The process is to use a strong oxidant to oxidize the surface of the steel into dense and smooth ferroferric oxide. This thin layer of ferroferric oxide can effectively protect the inside of the steel from oxidation. Divided into low temperature and high temperature.
Ferroferric oxide formed at low temperature (about 350°C) is dark black, also known as blackening. Ferroferric oxide formed by oxidation at high temperatures (about 550°C) is sky blue, also known as bluing treatment. The blue treatment is commonly used in weapon manufacturing, and the black treatment is commonly used in industrial production.
Oxidizing the steel surface to dense, smooth ferroferric oxide requires a strong oxidant. The strong oxidant is composed of sodium hydroxide, sodium nitrite, and trisodium phosphate. When it turns blue, treat the steel with a strong oxidant melt, and when it turns black, treat it with an aqueous solution of a strong oxidant.
Electroplating
Electroplating is the process of using electrolysis to coat a layer of other metal films or alloy films on the metal surface. The purpose is to improve wear resistance, corrosion resistance, and aesthetics.
There are 2 types of black plating: black zinc plating and black nickel plating.
Black zinc plating is a kind of anti-oxidation processing of metal, which is suitable for hardware products. Zinc is chemically active and easily oxidized and darkened in the atmosphere. After galvanizing, it is treated with chromate to cover a chemical conversion film on the zinc, so that the active metal is in a passive state, which is the passivation treatment of the zinc layer. The passivation film can be divided into white passivation (white zinc), light blue (blue zinc), black passivation (black zinc), green passivation (green zinc), etc.
Usually, the process of electroplating black zinc is degreasing-cleaning-weak acid etching-electro-galvanizing-cleaning-passivation-cleaning-drying-sealing paint.
The black nickel coating obtained from the black nickel bath contains 40-60% nickel, 20-30% zinc, 10-15% sulfur, and about 10% organic matter. The black color is caused by the presence of black nickel sulfide in the coating due to the reduction of thiocyanate on the cathode to release sulfide ions. The copper bottom is added in the process, and the main function is to make nickel plating easier in the post process and to improve the corrosion resistance of the screw.
Electrophoresis
Electrophoresis refers to the phenomenon in which charged particles move toward electrodes of opposite electrical properties under the action of an electric field.
Black electrophoresis is the use of an external electric field to make particles such as pigments and resins suspended in the electrophoresis solution directionally migrate and deposit on the substrate surface of one of the electrodes. Electrophoretic black is widely used in the industry, taking the black process as an example: degreasing – cleaning – phosphating – electrophoretic paint – drying. It can be divided into anodic electrophoresis (resin becomes negative ions after ionization) and cathodic electrophoresis (resin becomes positive ions after electrophoresis). Compared with the painting process, it has better construction performance, less pollution and harm to the environment and its resistance to neutral salt spray is 300 hours or more, and the cost and corrosion resistance are similar to those of the dacromet process.
Screws refer to a tool that gradually tightens a part using the mathematical and physical principles of the beveled circular rotation and friction of an object. Screws are a common fastener that is widely used in daily life and production. The general material is plastic or metal, and the grooves engraved on the surface are called threads, which are cylindrical.
Screws are ubiquitous in industrial production and daily life. Therefore, screws are also known as the rice of industry. The application scope of screws includes electronic products, mechanical products, digital products, power equipment, and electromechanical mechanical products. Screws are also widely used in vehicles, ships, chemical experiments, hydraulic engineering, and so on.
