Screws factory in China: Standard fasteners mainly include bolts, studs, screws, set screws, nuts, washers and rivets. There are many structural types of bolts, and most of the heads are hexagonal. For bolts subjected to impact, vibration or variable load, in order to increase flexibility, the polished rod part is made into a thin section or hollow. The seat end of the stud is screwed into the threaded hole of the connected piece, and the nut equipped with the nut end is similar to the bolt nut. The structure of the screw is roughly the same as that of the bolt, but the head shape is diverse to adapt to different assembly space, tightening degree and connection appearance. Set screws have different head and end shapes to accommodate different tightening degrees. There are also many types of nuts, with the hexagonal shape being the most widely used.

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.
Anodizing is a surface treatment used primarily for aluminum screws and fasteners. It enhances the natural oxide layer of aluminum, offering better corrosion resistance and a variety of color options. Anodized aluminum screws are available in various colors, such as clear, black, red, and blue. This treatment not only enhances the appearance but also increases the strength of the aluminum surface. Recommendation for Clients: Anodizing is a great choice for clients using aluminum screws in products where color customization is needed. It’s an excellent option for consumer electronics, jewelry, and decorative applications.
Rivets provide a permanent fastening solution for applications where disassembly is not required. Unlike screws and bolts, which can be easily removed and reused, rivets are designed to create a permanent joint. They consist of a smooth cylindrical shaft with a head on one end. The rivet is inserted through holes in the materials being joined, and then the tail end is deformed to create a second head, securing the materials together. Types of Rivets – Rivets come in various materials and designs to suit different applications. Some common types include: Solid rivets: These are the most common type, consisting of a solid shaft that is deformed to create a second head. Welcom to contact JM Hardware for this, we are one of the best solid rivet manufacturers. Read a lot more info at https://www.jm-fastener.com/.
Tailored Designs: The design and shape of non-standard nuts can vary widely, from traditional hex nuts and flange nuts to specialized designs such as wing nuts, knurled nuts, or captive nuts, adapted to specific installation, accessibility, or aesthetic considerations. Specialized Industries: Non-standard nuts find applications in specialized industries such as aerospace, automotive, marine, electronics, and medical devices, where standard nuts may not meet the unique demands of the application. Custom Machinery: These nuts are often used in custom machinery, equipment, and tooling where off-the-shelf fasteners cannot provide the required fit, strength, or performance.
Nylon-coated bolts feature a polymer coating applied to the surface, providing protection against corrosion and abrasion. The nylon coating acts as a barrier, preventing moisture and corrosive substances from reaching the underlying metal, making these bolts suitable for outdoor and marine applications. Choosing the right type of bolt is essential for preventing rust and corrosion in various applications. Stainless steel, galvanized, zinc-plated, aluminum, titanium, and nylon-coated bolts offer varying levels of corrosion resistance and durability. By selecting the appropriate type of bolt based on environmental conditions, load requirements, and cost considerations, engineers and manufacturers can ensure the longevity and reliability of assemblies while minimizing the risk of corrosion-related failures. Regular maintenance and inspection are also critical for identifying and addressing corrosion issues early, prolonging the lifespan of fasteners and enhancing overall performance and safety.
