Professional Applications & Engineering Value
This 3/8"-16 UNC steel set screw is engineered to address critical challenges in machinery assembly, automotive components, and construction equipment where vibration resistance and secure positioning are paramount. The square head design with external square drive allows for high-torque application, preventing slippage during tightening in confined spaces. Its cup point tip bites into the mating surface, creating a firm grip that withstands dynamic loads and thermal expansion. Made from hardened steel with Rockwell B80 hardness, it ensures durability against wear and fatigue, making it ideal for permanent or semi-permanent fastening in industrial settings. The coarse thread facilitates quick installation and reduces cross-threading risks, while the 4" length provides ample engagement for deep assemblies.
Specification Summary & Compliance
This set screw features a 3/8"-16 UNC coarse thread with Class 2A fit for precise dimensional accuracy and easy assembly. It complies with ASME B18.6.2 manufacturing specifications, ensuring consistent quality and performance. Environmental adherence includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free from hazardous substances and suitable for regulated industries.
