Professional Applications & Engineering Value
This black oxide alloy steel set screw delivers exceptional engineering value in industrial applications where vibration resistance and precise component positioning are critical. The Class 3A thread fit combined with UNF fine threads ensures superior clamping force retention in machinery, automotive components, and precision equipment. The extended tip design provides maximum contact surface for secure shaft-hub connections, while the headless configuration allows for flush mounting in space-constrained applications. The Rockwell C45 hardness guarantees durability under heavy loads, making these set screws ideal for permanent fastening solutions in manufacturing, automation systems, and power transmission equipment where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision and UNF 1/2"-20 fine threads. The set screw features a 2" length with extended tip design (0.13" tip length, 0.343" tip diameter) and 1/4" hex drive. Material certification includes alloy steel construction with black oxide surface treatment and Rockwell C45 hardness. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for international industrial applications.
