Professional Applications & Engineering Value

This 6-32 UNC coarse thread screw delivers exceptional engineering value through its 18-8 stainless steel composition and passivated finish, specifically engineered to combat corrosion in challenging industrial environments. The partially threaded design with Class 2A thread fit provides optimal clamping force while minimizing thread damage during repeated installations. The rounded head profile with standard slotted drive ensures compatibility with existing tooling while reducing stress concentration points. These industrial screws are particularly valuable in applications requiring reliable fastening where exposure to moisture, chemicals, or temperature variations would compromise inferior fasteners. The combination of 100,000 psi tensile strength and controlled Rockwell B100 hardness creates an ideal balance between durability and machinability for precision assemblies.

Specification Summary & Compliance

This fastener maintains precise Class 2A thread fit tolerances per UNC standards with 6-32 coarse threading and right-hand thread direction. Manufacturing and dimensional compliance strictly adhere to ASME B18.6.3 specifications. Environmental regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring suitability for global industrial markets. The 3" length with minimum 1½" thread length provides consistent engagement characteristics across applications.
