Excellent custom machine screws manufacturer and supplier: Types of Screws – A wide variety of custom made screws are available, each optimized for specific applications. Some common types include: Wood screws: These screws have a tapered shaft and a coarse thread, specifically designed for use in wood. Machine screws: Used for fastening metal components, custom machine screws have a cylindrical shaft and are available with a variety of head types, such as flat, oval, and pan heads. Self-tapping screws: These screws form their own thread as they are driven into the material, eliminating the need for a pre-tapped hole. Drywall screws: Designed for fastening drywall to studs, drywall screws have a bugle head and a coarse thread. See even more info at custom machine fasteners.
Chromate conversion coating is a type of treatment that is often used for screws made of aluminum, zinc, or magnesium alloys. It provides a clear or iridescent finish that improves corrosion resistance and gives the screw a more refined, shiny appearance. This finish is commonly used in the aerospace industry and for electronic components. Recommendation for Clients: If the client requires a high-performance screw with a professional, high-end finish, chromate conversion coating is a great choice. However, this process is typically more expensive than zinc plating, so it should be used for specialized, high-end applications.
Automotive Industry (240–500 Hours): Automotive fasteners used in automobiles, particularly in parts exposed to weather, moisture, and road salt, require 240 to 500-hour salt spray tests. These fasteners are often coated with protective layers, such as zinc plating, to prevent corrosion and maintain their integrity. Corrosion resistance is crucial for automotive safety components, such as suspension bolts, brake systems, and body parts. Aerospace Industry (500–1000 Hours): Aerospace fasteners, which are used in aircraft, helicopters, and spacecraft, are subject to harsh conditions, including high altitudes, humidity, and temperature extremes. As such, these fasteners typically undergo 500 to 1000-hour salt spray tests to ensure their reliability in demanding environments. Aerospace fasteners are often made of high-strength alloys and are coated with special corrosion-resistant materials to ensure their performance over extended periods.
Micro Screws, also known as ‘tiny screws’ or ‘nano screws’, are a type of specialist fastener that is significantly smaller and lighter than the average precision screw. Micro Screws are available in a wide range of materials including steel, stainless steel, brass, nylon, aluminium and titanium as well as exotic materials.Micro screw for electronics are extremely important.Businesses can use micro screws to keep electronic components fastened together and working properly.In addition, micro machine screws can be used for the automotive Industry, computer technologies, telecommunications, consumer products, medical instruments, optical devices, industrial products, and much more. Want to know more, contact Chuanghe Fastener Co., ltd., we are one of the most professional micro screw manufacturers in China.
Small thumb screws can be as short as 4mm or less from the shoulder to the end of the threading, while long thumb screws commonly extend to around 25-30mm (1 inch) and beyond. It is unusual to find very long thumb screws for most day-to-day fastening jobs. Flat Head Screws, also called Countersunk Screws, are conical with a flat outer face and a tapering inner face. An advantage to this type of screw is that very little of the head protrudes beyond the surface, allowing it to sink into the material.
Captive screws, also known as captive panel screws or captive fasteners, feature a permanently attached washer or retainer that prevents the screw from becoming lost or misplaced. They are commonly used in equipment enclosures, access panels, and electronic devices where frequent maintenance or servicing is required. Shoulder screws, also known as shoulder bolts or stripper bolts, feature a cylindrical shoulder between the head and the threads. They are used in applications requiring precise alignment or spacing, such as machinery, automotive components, and tooling fixtures. Shoulder screws may have hex, socket, or slotted heads and are available with various shoulder diameters and lengths. See even more info on che-parts.com.
Bolts can provide a more substantial clamping force due to the use of nuts. This force ensures that the assembled components are held together tightly, minimizing the risk of loosening under vibration or dynamic loads. This is particularly important in applications where stability and security are paramount, such as in structural steel frameworks and engine assemblies. One significant advantage of bolts is their ease of disassembly and reassembly. Bolts can be removed and replaced without damaging the components they secure. This makes them ideal for applications that require regular maintenance, adjustments, or repairs, such as in mechanical systems, vehicles, and industrial equipment.

Enhanced Security: Bolts provide enhanced security in critical applications. For example, tamper-proof bolts are used in public infrastructure and high-security installations to prevent unauthorized disassembly. The ability to use locking mechanisms, such as lock nuts or thread-locking compounds, further enhances the security and reliability of bolted connections. Compatibility with High-Strength Applications: Bolts are better suited for high-strength applications due to their robust design and the ability to use high-grade materials. Grade 8 or 10.9 bolts, for example, offer exceptional tensile strength and are used in demanding environments such as automotive suspensions and heavy machinery.
