• Enhanced load distribution from the wide rounded truss head design, reducing surface damage and improving joint integrity
• High tensile strength of 100,000 psi ensures reliable performance under heavy mechanical stress
• Quick and secure installation with coarse 6-32 UNC threading and Class 2A fit, minimizing cross-threading risks
• Full threading along the 1" length provides maximum grip and uniform clamping force
• Durable Rockwell B100 hardness maintains thread integrity and resists wear over repeated use
• Compliance with ASME B18.6.3, RoHS 3, and REACH guarantees quality, safety, and environmental standards

Professional Applications & Engineering Value

Engineered for demanding industrial settings, this 6-32 UNC coarse thread screw in 18-8 stainless steel addresses common challenges like corrosion, vibration loosening, and assembly efficiency. The rounded truss head offers a wider bearing surface, distributing pressure evenly to prevent material indentation in soft substrates or sheet metal. Combined with a passivated finish, it resists oxidation and chemical exposure in automotive, electronics, and outdoor equipment. The coarse threading and Class 2A fit enable faster installation with reduced galling, while the fully threaded design ensures consistent holding power in high-stress applications, from machinery frames to structural assemblies.

Specification Summary & Compliance

This screw adheres to Class 2A thread fit per UNC standards, ensuring precise dimensional accuracy and interchangeability. Manufacturing follows ASME B18.6.3 specifications for consistency and reliability. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances for safe industrial use.
