Professional Applications & Engineering Value

These black-oxide steel setup studs are engineered to solve critical alignment challenges in precision manufacturing and machinery setup. The threaded both ends design with 1/4"-20 threading enables secure temporary fixturing in jigs, fixtures, and workholding applications where repeated assembly and disassembly are required. The Class 2A thread fit provides optimal clearance for quick installation while maintaining positional accuracy, significantly reducing setup time in production environments. The black-oxide surface treatment offers superior corrosion protection compared to plain steel, extending component life in workshops with moderate humidity or coolant exposure. These DIN 939 compliant studs deliver consistent performance in CNC machining centers, inspection equipment setup, and precision assembly lines where dimensional stability is paramount.

Specification Summary & Compliance

Manufactured to exacting standards, these setup studs feature Class 2A thread fit per ANSI/ASME B1.1 specifications, ensuring proper clearance and assembly characteristics. The DIN 939 manufacturing standard guarantees dimensional consistency and mechanical properties for reliable performance. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) adherence, confirming the absence of restricted substances. Mechanical properties exceed 125,000 psi minimum tensile strength and Rockwell C22 hardness, providing assurance of structural integrity in demanding applications.
