Professional Applications & Engineering Value

Engineered for demanding industrial applications, this hex headless set screw delivers reliable performance in machinery assembly, automotive components, and precision equipment. The 18-8 stainless steel construction provides excellent corrosion resistance, while the Class 3A thread fit ensures tight tolerances for vibration-prone environments. The cup point design creates permanent seating in shafts and collars, preventing slippage under torque loads. With 4" length and coarse UNC threading, it offers optimal engagement depth for heavy-duty fastening requirements. The right-hand thread direction and hex drive style enable quick installation in confined spaces where traditional headed fasteners cannot be used.

Specification Summary & Compliance

This set screw maintains Class 3A thread fit precision according to UNC standards with 1/2"-13 thread size and coarse thread spacing. Manufactured to meet ASME B18.3 specifications for dimensional accuracy and performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors.
