• Regulatory compliance meeting RoHS 3 and REACH environmental standards for global manufacturing applications

Professional Applications & Engineering Value

This black oxide alloy steel set screw delivers exceptional engineering value in precision assembly applications where vibration resistance and space constraints are critical concerns. The extended tip design (0.098" length) provides deeper engagement with mating components, effectively preventing loosening under dynamic loads. Manufactured from high-strength alloy steel with Rockwell C45 hardness, this fastener maintains structural integrity in high-stress applications while the 10-32 UNF fine threads offer superior holding power compared to coarse thread alternatives. The headless configuration and 3/32" hex drive make it ideal for machinery, automotive components, and precision instruments where flush mounting and reliable installation are paramount for operational safety and performance.

Specification Summary & Compliance

This precision set screw features 10-32 UNF Class 3A threads with fine thread spacing, manufactured to ASME B18.3 specifications. The extended tip maintains tight dimensional tolerances (tip diameter: 0.127" ±0.007", tip length: 0.098" -0.005" to 0") for consistent performance. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications requiring strict material composition controls.
