Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications where vibration resistance and permanent positioning are paramount. The Class 3A UNC coarse thread provides superior engagement in soft materials and castings, while the cup tip design creates permanent dimples in shafts and collars to prevent rotational slippage. Manufactured from high-strength alloy steel with Rockwell C45 hardness, it withstands extreme mechanical stresses in machinery, automotive components, and power transmission systems. The black-oxide surface treatment offers moderate corrosion protection where lubricants are present, making it ideal for industrial set screw applications requiring reliable, semi-permanent fastening solutions.
Specification Summary & Compliance
This set screw maintains precision Class 3A thread fit with 3/8"-16 UNC coarse thread configuration and 1/2" length. Manufactured to ASME B18.3 specifications and ASTM F912 material standards, it ensures dimensional accuracy and mechanical performance. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting current substance restriction requirements for industrial use.
