Professional Applications & Engineering Value
This 5/16"-18 UNC Class 3A set screw delivers critical engineering solutions for industrial assembly challenges. The 18-8 Stainless Steel composition provides excellent corrosion resistance, making it ideal for machinery exposed to moisture, chemicals, or outdoor elements. The hex headless design with 5/32" drive allows installation in confined spaces while maintaining high torque capability. The cup point tip creates permanent indentation in shafts and collars, preventing rotational slippage in high-vibration applications like motor mounts, gear assemblies, and precision equipment. With coarse UNC threads and Class 3A fit, this set screw ensures rapid installation and superior clamping force for permanent positioning requirements across manufacturing, automotive, and heavy equipment sectors.
Specification Summary & Compliance
This set screw maintains precision Class 3A thread fit with 5/16"-18 UNC coarse threads and right-hand direction. Manufacturing complies with ASME B18.3 standards for dimensional accuracy and performance. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting international environmental regulations for hazardous substance restrictions.
