• High mechanical strength with 120,000 psi tensile rating and Rockwell C39 hardness, resisting deformation under heavy loads
• Optimized head profile with rounded button design, providing flush mounting while maintaining high drive integrity
• Full threading coverage along the 1/4" length, enabling maximum grip across the entire fastener engagement
• Regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial use

Professional Applications & Engineering Value

These Black-Oxide Alloy Steel rounded head screws deliver critical performance advantages in precision assembly applications where vibration resistance and consistent clamping force are paramount. The 10-32 UNF fine thread configuration with Class 3A tolerance ensures superior thread engagement in tapped holes, reducing the risk of cross-threading in automated production environments. The T25 Torx Plus drive system addresses common installation challenges by providing exceptional torque transfer without the slippage common to Phillips or standard Torx drives. This combination of high-strength alloy material (Rockwell C39 hardness) and advanced drive technology makes these fasteners ideal for electronics enclosures, machinery guards, and precision instrumentation where reliable, repeatable fastening is essential.

Specification Summary & Compliance

Manufactured to exacting inch system dimensions with Class 3A thread fit per UNF standards, ensuring precise interchangeability. These screws conform to ASME B18.3 specifications (ASTM F835) for dimensional consistency and mechanical properties. The Black-Oxide surface treatment provides corrosion protection while maintaining dimensional integrity. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance for industrial and commercial applications.
