Professional Applications & Engineering Value

This black-oxide steel setup stud addresses critical alignment challenges in precision machinery and fixture applications. The double-ended threading configuration allows simultaneous secure mounting at both connection points, eliminating misalignment issues in industrial assembly processes. With differential thread lengths (2 1/2" and 3/8"), engineers gain installation flexibility while maintaining the high tensile strength required for vibration-resistant connections. The black-oxide surface treatment provides essential corrosion protection in manufacturing environments where moisture and chemicals are present, significantly reducing maintenance intervals and replacement costs. Compliant with DIN 939 standards, this component ensures interoperability in global equipment designs and automated production systems.

Specification Summary & Compliance

Manufactured to Class 2A thread fit tolerances with 1/4"-20 threading on both ends, this setup stud maintains dimensional accuracy per DIN 939 specifications. The component achieves 125,000 psi minimum tensile strength and Rockwell C22 hardness for consistent mechanical performance. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, ensuring adherence to international substance restriction standards for industrial components.
