Professional Applications & Engineering Value

This 1/2"-13 UNC hex headless set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. The 18-8 stainless steel construction provides excellent corrosion resistance for machinery operating in humid or chemical-exposed environments. The permanent swivel tip technology, made from 304 stainless steel, creates a secure locking mechanism that prevents components from shifting under continuous vibration - a common failure point in industrial equipment. With its Class 2A thread fit and coarse thread spacing, this fastener ensures rapid installation while maintaining precise alignment in assemblies requiring maximum holding power. The combination of Rockwell C54 hardness and 9° maximum swivel angle makes it ideal for permanent positioning applications in power transmission systems, manufacturing equipment, and precision machinery where reliability cannot be compromised.

Specification Summary & Compliance

This set screw features 1/2"-13 UNC coarse threads with Class 2A thread fit for standard industrial applications. The 0.5" thread diameter and 1" length provide consistent dimensional accuracy, while the right-hand thread direction and hex drive style ensure compatibility with common installation tools. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, guaranteeing safe use across various industrial sectors without hazardous substance restrictions.
