Professional Applications & Engineering Value
This 8-32 UNC set screw delivers critical engineering solutions where vibration resistance and permanent positioning are paramount. The 18-8 stainless steel material provides excellent corrosion resistance, making it ideal for industrial machinery, automotive assemblies, and outdoor equipment exposed to moisture and chemicals. The hex headless design allows for flush mounting in confined spaces, while the cup point tip creates permanent indentation in shafts and collars, preventing rotational slippage under high torque conditions. With its Class 3A thread fit and coarse UNC thread spacing, this fastener ensures quick assembly and disassembly while maintaining precise alignment in power transmission systems and precision instruments.
Specification Summary & Compliance
This set screw features 8-32 UNC coarse threads with Class 3A thread fit for superior precision and right-hand thread direction for standard applications. Manufacturing complies with ASME B18.3 specifications ensuring dimensional accuracy and performance reliability. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting current environmental regulations for hazardous substance restrictions.
