Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers exceptional engineering value in demanding industrial environments where vibration resistance and surface protection are critical. The Class 3A thread fit provides superior engagement with mating components, significantly reducing the risk of loosening under dynamic loads. The nylon 6/6 plastic tip offers dual benefits: it prevents damage to expensive machinery surfaces while maintaining consistent clamping force across a wide temperature range from -50° to 250°F. Ideal for precision equipment, automotive assemblies, and manufacturing machinery, this hex drive set screw combines the strength of alloy steel with the corrosion resistance of black-oxide finishing, ensuring long-term reliability in applications where standard fasteners would fail.
Specification Summary & Compliance
Manufactured to exacting standards with 1/2"-13 UNC Class 3A threads and precise dimensional tolerances. This set screw meets ASME B18.3 specifications for dimensional requirements and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The right-hand coarse threads provide optimal engagement in most industrial applications, while the Rockwell C28 hardness ensures consistent performance under mechanical stress.
