Professional Applications & Engineering Value

Engineered for industrial and mechanical fastening, this Phillips pan head screw with lock washer addresses critical challenges like vibration-induced loosening and environmental degradation. The 18-8 Stainless Steel construction, enhanced by a passivated finish, offers excellent resistance to corrosion, making it suitable for outdoor, marine, or chemical-exposed settings. The internal-tooth lock washer (made from 410 Stainless Steel) bites into surfaces to maintain clamp load, reducing maintenance needs in machinery, automotive, and electronics assemblies. With a coarse UNC 6-32 thread and fully threaded design, it ensures rapid installation and secure holding in metals or plastics, streamlining production while upholding 70,000 psi tensile strength for high-stress applications.

Specification Summary & Compliance

This screw features precise Class 2A thread fit and UNC coarse threads for consistent performance. It meets ASME B18.13 specifications for dimensional accuracy and is fully RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliant, ensuring adherence to environmental and safety regulations. The combination of 18-8 Stainless Steel for the screw and 410 Stainless Steel for the washer, both with passivated finishes, supports durability and regulatory standards in global supply chains.
