- Space-saving installation through headless design ideal for confined spaces and flush mounting requirements
Professional Applications & Engineering Value
This 8-32 UNC set screw delivers critical engineering solutions for industrial assembly challenges where vibration resistance and permanent positioning are paramount. The zinc plated alloy steel construction provides essential corrosion protection while maintaining Rockwell C45 hardness for long-term performance in machinery, automotive components, and precision equipment. The cup tip design creates concentrated pressure points that prevent shaft slippage in pulleys, collars, and gears, while the 5/64" hex drive ensures secure tool engagement during installation. Engineered with Class 3A thread fit and coarse UNC threads, this headless fastener offers reliable performance in high-vibration environments where loosening could cause equipment failure or safety hazards.
Specification Summary & Compliance
This precision set screw maintains Class 3A thread fit tolerances with 8-32 UNC coarse threads and right-hand thread direction. Manufactured to ASME B18.3 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The product features a consistent 3/8" length and 0.164" thread diameter with cup tip configuration, ensuring repeatable performance across industrial applications.
