Professional Applications & Engineering Value
This black-oxide alloy steel set screw delivers critical engineering solutions for industrial machinery, automotive systems, and precision equipment. The Class 3A thread fit maintains tight tolerances in vibrating environments, while the oval tip design distributes clamping force evenly to prevent component damage. Manufactured to ASME B18.3 specifications, these headless set screws provide reliable positioning of gears, pulleys, and collars where flush mounting is essential. The hex drive configuration ensures secure tool engagement during installation, reducing the risk of stripped fasteners in high-torque applications. With Rockwell C45 hardness, these fasteners withstand repeated adjustments without deformation, making them ideal for maintenance-intensive operations.
Specification Summary & Compliance
Precision-engineered with 1/4"-20 UNC coarse threads and Class 3A thread fit for superior dimensional accuracy. Manufactured in compliance with ASME B18.3 specifications where applicable under ASTM F912. Meets environmental regulations including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance standards. Right-hand thread direction with 1-1/4" length provides consistent engagement depth across industrial applications.
