Professional Applications & Engineering Value
These black-oxide steel setup studs address critical alignment challenges in precision assembly systems. The 3/8"-16 threading on both ends enables symmetrical load distribution while the 1 1/4" thread length provides sufficient engagement depth for vibration-resistant connections. Engineered to DIN 939 standards, these studs maintain positional accuracy in jigs, fixtures, and machining setups where repetitive disassembly is required. The 125,000 psi tensile strength combined with Rockwell C22 hardness ensures dimensional stability under cyclical loading, making them ideal for automotive tooling, industrial machinery alignment, and precision manufacturing applications where reliability cannot be compromised.
Specification Summary & Compliance
Manufactured to Class 2A thread fit tolerances with 3/8"-16 unified threads on both ends. Complies with DIN 939 specifications for dimensional accuracy and mechanical properties. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for hazardous substance restrictions. All measurements conform to inch system standards with documented material certifications available.
