Professional Applications & Engineering Value
This 6-32 UNC set screw delivers critical engineering solutions for industrial applications where component slippage can cause equipment failure. The zinc plated alloy steel construction provides excellent corrosion protection while maintaining the Rockwell C45 hardness needed for repeated adjustments without deformation. The headless hex drive design allows for flush mounting in confined spaces, while the cup tip creates concentrated pressure points that prevent rotational movement of gears, pulleys, and collars on shafts. With Class 3A thread fit and coarse thread spacing, this fastener ensures rapid installation and reliable performance in high-vibration environments common in machinery, automotive, and manufacturing equipment.
Specification Summary & Compliance
This set screw features precise 6-32 UNC thread with Class 3A thread fit per ASME standards, ensuring tight tolerances for secure fastening. The 3/8" length and 0.138" thread diameter provide optimal engagement depth for various applications. Manufactured to ASME B18.3 specifications and ASTM F912 standards, this component maintains consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for use in regulated industries and international markets.
