Our high-performance red dot sight screw set is designed to meet the strict demands of precision mounting applications. Made from 12.9 grade carbon steel with a durable black oxide finish, these screws deliver exceptional strength, corrosion resistance, and reliable performance. The kit includes M3, M3.5, and M4 torx flat head screws in 4 lengths (6mm, 8mm, 10mm, 12mm), plus M4 torx socket head bolts, M4 hex set screws, and matching L-shaped torx and hex wrenches. Each screw features tight dimensional tolerances for secure, wobble-free mounting of red dot sights, optics, and accessories. As a professional fastener manufacturer, we offer full custom service and OEM support to tailor these fasteners to your specific mounting requirements.
