Professional Applications & Engineering Value

These black-oxide steel setup studs address critical challenges in machinery assembly and precision fixturing. The 1"-8 threading on both ends with Class 2A thread fit ensures accurate alignment and secure fastening in jigs, molds, and industrial equipment, minimizing vibration-induced loosening. The black-oxide surface treatment provides a protective layer against rust and corrosion, extending component life in humid or abrasive settings. With a 125,000 psi tensile strength and Rockwell C22 hardness, these studs maintain structural integrity under heavy loads and repeated use, making them ideal for CNC machining setups, automotive tooling, and heavy-duty manufacturing applications where reliability and dimensional stability are paramount.

Specification Summary & Compliance

Manufactured to DIN 939 specifications, these setup studs feature Class 2A thread fit for consistent dimensional accuracy and interchangeability. The 7" length with 2 1/2" threaded sections on both ends adheres to standardized engineering tolerances. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for global industrial use.
