Professional Applications & Engineering Value

This 3/8"-16 UNC set screw delivers critical engineering solutions for industrial applications requiring permanent component positioning. The alloy steel construction with Rockwell C45 hardness provides exceptional resistance to vibrational stresses and mechanical wear in power transmission systems, machinery assemblies, and precision equipment. The nylon patch locking technology creates consistent friction that prevents back-off without compromising the Class 3A thread fit integrity, while the extended tip design ensures maximum contact surface for secure shaft-hub connections. Engineered for heavy-duty applications where reliability is paramount, this headless set screw with coarse thread spacing offers quick installation and long-term performance stability in manufacturing, automotive, and industrial equipment sectors.

Specification Summary & Compliance

This set screw features precision 3/8"-16 UNC threads with Class 3A external thread fit and coarse thread spacing for optimal engagement. The extended tip maintains tight dimensional control with 0.25" diameter and length tolerance of -0.01" to 0". Manufacturing complies with ASME B18.3 specifications where applicable, with full conformity to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards for industrial use.
