Professional Applications & Engineering Value

This 18-8 stainless steel hex headless set screw delivers critical engineering solutions for industrial applications where vibration resistance and permanent positioning are paramount. The Class 3A thread fit provides tighter tolerances than standard fasteners, eliminating play in precision assemblies while the cup point design bites into mating surfaces to prevent rotational movement under dynamic loads. Manufactured from corrosion-resistant 18-8 stainless steel, this UNC threaded set screw maintains integrity in humid or chemically aggressive environments common in manufacturing, automotive, and heavy equipment applications. The 1/4" hex drive accommodates standard tools for efficient installation in confined spaces where headless design is essential.

Specification Summary & Compliance

This 1/2"-13 UNC set screw features precision Class 3A thread fit with coarse thread spacing for optimal engagement strength. Manufactured to ASME B18.3 specifications, it ensures dimensional accuracy and performance reliability. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances. With a standardized 1-1/2" length and right-hand thread direction, this industrial-grade set screw meets rigorous quality standards for professional applications.
