Professional Applications & Engineering Value
This 10-32 UNF set screw delivers critical engineering solutions for industrial equipment requiring precision fastening with surface protection. The black-oxide alloy steel construction provides excellent corrosion resistance while maintaining Rockwell C28 hardness for structural integrity. The Class 3A thread fit ensures zero backlash in high-vibration applications like motor mounts, conveyor systems, and precision machinery. The integrated brass soft tip prevents galling and surface damage on shafts, gears, and rotating components while distributing clamping force evenly. Compliant with ASME B18.3 specifications, these headless set screws with hex drive installation are indispensable for maintenance operations and OEM assembly where space limitations and reliability are paramount concerns.
Specification Summary & Compliance
Manufactured to ASME B18.3 standards with Class 3A thread fit for superior dimensional accuracy in 10-32 UNF fine threading. The black-oxide alloy steel construction delivers consistent performance with Rockwell C28 hardness rating. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations ensures safe industrial usage. Right-hand thread direction with precise 0.19" thread diameter and 3/4" length provides standardized interoperability across equipment platforms.
