• Guaranteed compliance and quality meeting ASME B18.3, ASTM F879, RoHS 3, and REACH standards

Professional Applications & Engineering Value

Engineered for precision assembly, these 10-32 UNF Class 3A rounded head screws provide a robust fastening solution where reliability is non-negotiable. The 18-8 stainless steel material combined with a passivated finish offers excellent resistance to oxidation and chemical exposure, making them suitable for electronics, automotive, and machinery applications exposed to moisture or corrosive agents. The T25 Torx drive ensures high torque transfer with minimal tool slippage, protecting the screw head and speeding up installation in high-volume production lines. Their fine thread spacing and Class 3A fit deliver superior clamping force and vibration resistance, preventing loosening in dynamic or high-stress environments.

Specification Summary & Compliance

This fastener adheres to Class 3A thread tolerances for precision fit, manufactured in accordance with ASME B18.3 and ASTM F879 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material transparency. The screw features a right-hand, fully threaded design with a 10-32 UNF thread size and 1" length in the inch measurement system.
