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.

Screws are ubiquitous custom automotive fasteners found in a vast range of industries and everyday applications, including: Construction: Screws are essential for fastening wood framing, drywall, and other building materials in residential and commercial construction. Manufacturing: They play a crucial role in assembling machinery, electronics, and consumer products. Automotive: Screws are used extensively in the automotive industry to secure various components in vehicles. DIY projects: From furniture assembly to home repairs, custom made screws are indispensable for countless tasks around the house. When selecting a screw, carefully consider the material you’re fastening, the required holding strength, and the desired aesthetics to ensure optimal performance and longevity.

Recommendation for Clients: For customers looking for an attractive finish without high costs, zinc plating in clear or black is an excellent option. This process enhances the screw’s appearance while providing basic corrosion resistance. Black oxide is another popular surface treatment that gives custom made screws a sleek, matte black finish. This finish is commonly used for decorative purposes and for applications where a non-reflective, uniform appearance is desired. Black oxide also offers moderate corrosion resistance, especially when combined with oil or wax coatings. Recommendation for Clients: If the client prefers a non-reflective, black finish with a slightly more industrial aesthetic, black oxide is a cost-effective option. This finish is often chosen for applications in automotive interiors and some consumer electronics. See even more info on https://www.jm-fastener.com/.

In construction, bolts are often preferred for structural connections. Steel beams, columns, and trusses are typically joined using bolts to ensure a secure and stable framework. The high load-bearing capacity and ease of disassembly make bolts ideal for temporary structures, such as scaffolding, as well as permanent installations. Automotive Industry: The automotive industry relies heavily on bolts for assembling engines, transmissions, suspensions, and other critical components. The ability to withstand high loads and vibrations ensures the reliability and safety of vehicles. Bolts also allow for easy maintenance and replacement of parts, which is essential for vehicle longevity and performance.

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.
