Professional Applications & Engineering Value
This black-oxide steel setup stud delivers critical engineering value in jig and fixture applications where alignment accuracy and repeated assembly are paramount. The threaded both ends design enables secure connections between components, reducing setup time while maintaining positional stability under vibration. Its high tensile strength (125,000 psi) and hardened steel core prevent thread stripping and elongation in high-cycle industrial equipment. Complying with DIN 939, this stud ensures dimensional consistency for European and global tooling systems, while the black-oxide finish resists oil and moisture, extending service intervals in CNC machining, automotive assembly, and heavy machinery maintenance.
Specification Summary & Compliance
This setup stud maintains Class 2A thread fit per inch standards, with precise 1/2"-13 threading and 3 1/2" overall length. Manufacturing adheres to DIN 939 specifications for dimensional integrity. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in international industrial supply chains.
