Professional Applications & Engineering Value

This alloy steel set screw with nylon patch thread locker addresses critical vibration-induced loosening in industrial machinery, automotive components, and heavy equipment. The Class 3A external thread fit provides superior dimensional accuracy for precise mating with internal threads, eliminating play in high-stress assemblies. The extended tip design ensures positive contact and seating in blind holes, while the Rockwell C45 hardness maintains thread integrity under repeated loading. Ideal for permanent fastening applications where vibration resistance and thermal stability up to 250°F are essential, this UNC coarse thread set screw delivers reliable performance in production environments requiring consistent clamping force.

Specification Summary & Compliance

Manufactured to ASME B18.3 specifications with Class 3A external thread fit and 1/2"-13 UNC coarse thread profile. The extended tip features diameter tolerance of -0.01" to 0" and length tolerance of -0.01" to 0". Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors.
