Professional Applications & Engineering Value
This Black-Oxide Alloy Steel set screw delivers critical engineering solutions for industrial equipment, machinery, and precision assemblies. The Class 3A thread fit and coarse UNC threads ensure zero backlash in high-vibration environments, preventing loosening in motors, gears, and coupling systems. Its headless hex drive design allows flush mounting in confined spaces while maintaining high torque capability. The Rockwell C45 hardness provides excellent wear resistance, making it ideal for permanent positioning applications where corrosion resistance and long-term reliability are paramount. Engineered to ASME B18.3 specifications, this set screw meets the demanding requirements of automotive, aerospace, and heavy equipment manufacturing sectors.
Specification Summary & Compliance
This set screw maintains precision Class 3A thread tolerances with 1/4"-20 UNC coarse threads and flat tip configuration. Manufactured to ASME B18.3 specifications (ASTM F912) with complete compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The inch-system measurement ensures compatibility with North American industrial equipment and replacement part requirements.
