- Precise thread engagement with Class 3A fit and UNF fine threads, ensuring vibration-resistant, secure fastening in precision assemblies
- Optimized torque transmission via 3/32" hex drive and headless design, ideal for confined spaces requiring flush mounting
- Enhanced grip and component retention with cup tip design, minimizing slippage on shafts and axles
- Regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial use
- Reliable right-hand threading with 10-32 fine spacing, providing consistent clamping force in dynamic applications
Professional Applications & Engineering Value
This 10-32 UNF Class 3A set screw delivers critical performance in precision machinery, automotive components, and electrical enclosures where vibration resistance and positional accuracy are paramount. The zinc plated alloy steel construction combats environmental degradation while maintaining Rockwell C45 hardness to withstand repeated adjustments. Its headless hex drive and fine thread spacing enable flush installation in tight tolerances, preventing interference in rotating assemblies. The cup tip securely bites into shafts without causing material damage, solving common slippage issues in power transmission systems. Engineered to ASME B18.3 specifications, this fastener ensures dimensional consistency across high-volume production runs.
Specification Summary & Compliance
Manufactured to Class 3A thread fit tolerances per UNF standards with precise 10-32 fine threading and 5/8" length. Complies with ASME B18.3 dimensional requirements and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for hazardous substance restrictions. The right-hand thread direction and 3/32" hex drive conform to industrial assembly specifications for consistent performance.
