Professional Applications & Engineering Value
This 6-32 UNC set screw delivers critical engineering solutions for industrial machinery, automotive assemblies, and precision equipment. The black-oxide alloy steel construction provides excellent corrosion protection while maintaining Rockwell C45 hardness for enduring mechanical performance under repetitive stress. Its headless design with hex drive enables flush mounting in confined spaces, while the cup tip ensures positive seating on shaft surfaces without marring components. The Class 3A thread fit guarantees precise tolerances for vibration-resistant fastening in high-torque applications, making it ideal for permanent positioning of gears, pulleys, and collars where reliability is paramount.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with ASTM F912 material standards, this set screw maintains Class 3A thread fit precision with UNC coarse threading at 6-32 size. The 1-1/4" length and 0.138" thread diameter provide consistent dimensional accuracy. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and material traceability for global industrial applications.
