Professional Applications & Engineering Value
Engineered for demanding industrial applications, this black-oxide alloy steel set screw delivers reliable performance where vibration resistance and corrosion protection are critical. The UNC coarse thread with Class 3A fit provides superior clamping force in machinery, automotive components, and power transmission systems, preventing joint failure under cyclic loading. The hex socket drive enables high-torque installation in confined spaces, while the cup point tip bites securely into shafts and collars, maintaining positional accuracy in precision assemblies. Ideal for permanent fastening in heavy equipment, manufacturing fixtures, and aerospace components requiring ASME B18.3 compliance and environmental regulation adherence.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with UNC 3/8"-16 coarse threads and Class 3A thread fit for precision dimensional accuracy. The 1-1/2" length and 0.375" thread diameter maintain consistent engagement depth. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, with material hardness verified at Rockwell C45 for guaranteed mechanical performance.
