Stainless steel set screw manufacturer – specializing in non-standard fastener production
M2, M4, M5, and M6 stainless steel set screws with polyurethane (PU) tips are designed for applications requiring secure positioning and surface protection. Unlike traditional metal set screws, this design combines a stainless steel screw body with a soft polyurethane (PU) tip, providing clamping force while reducing direct metal-to-metal contact with the workpiece. The PU tip is particularly suitable for bumpers, protective components, coated surfaces, plastic parts, aluminum profiles, and other applications where standard metal-tipped set screws may leave marks or cause surface damage.
ZeYao, a non-standard fastener manufacturer with over 20 years of production experience, can customize stainless steel set screws according to customer drawings, samples, and application requirements, including different screw sizes, thread specifications, PU tip sizes, colors, hardness, and surface finishes.
About Stainless Steel Set Screws
These screws are made of 304 stainless steel, making them extremely strong and suitable for both indoor and outdoor use.
The threads are evenly pitched, clearly visible, and burr-free. The threads enhance the screw's grip, preventing it from loosening or falling off prematurely.
Stainless steel hardware is ideal for use in humid environments. They are robust, durable, and high-performing, meeting the needs of all your projects.
Versatile Applications: You can use a variety of hex socket head cap screws to secure door handles, faucets, locks, bathroom fixtures, toys, pipes, knobs, taps and repair supplies, musical instruments, and electronics in shops, garages, or homes.
