Professional Applications & Engineering Value
These 6-40 UNF set screws deliver exceptional engineering value in applications requiring precise component positioning and secure fastening. The 18-8 stainless steel composition provides excellent resistance to corrosion and oxidation, making them ideal for machinery, automotive assemblies, and electronic enclosures exposed to moisture or chemicals. The headless design with 1/16" hex drive allows for flush mounting in confined spaces while maintaining high torque capability. The Class 3A thread fit and fine UNF threading ensure vibration resistance and prevent loosening in dynamic applications. The cup tip design creates concentrated pressure points for superior grip on shafts, collars, and pulleys, solving common slippage issues in power transmission systems.
Specification Summary & Compliance
This set screw features precise Class 3A thread fit tolerance with 6-40 UNF fine threads, 0.138" thread diameter, and 3/16" length. Manufactured to ASME B18.3 specifications for dimensional accuracy and interchangeability. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors. Right-hand thread direction and Rockwell B80 hardness provide consistent performance in demanding applications.
