  • Compliance with ASME B18.3, RoHS 3, and REACH guarantees quality, safety, and environmental standards are met.

Professional Applications & Engineering Value

These 6-32 UNC flat head screws are engineered to address common industrial challenges such as material fatigue and environmental degradation. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to rust and chemicals, making them suitable for applications in machinery, electronics, and outdoor equipment. The Class 3A thread fit and coarse thread spacing ensure quick, secure fastening with minimal risk of cross-threading, while the 82° countersink angle allows the screw to sit flush with surfaces, reducing snagging and improving aesthetics. This design is ideal for assemblies requiring high strength and durability, such as in automotive, aerospace, and heavy-duty manufacturing, where reliability is critical.

Specification Summary & Compliance

This product features a 6-32 UNC thread size with Class 3A thread fit for precise dimensional accuracy, ensuring consistent performance. It is manufactured in accordance with ASME B18.3 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental and safety standards for industrial use.
