Professional Applications & Engineering Value
These black-oxide steel setup studs deliver critical engineering solutions for industrial machinery assembly, fixture manufacturing, and precision equipment alignment. The 1/2"-13 threading with Class 2A fit eliminates play in connections while the double-ended design enables efficient temporary mounting and disassembly in production environments. The 125,000 psi tensile strength combined with Rockwell C22 hardness ensures dimensional stability under vibration and load variations, making them ideal for CNC machine setups, automotive jigs, and heavy equipment manufacturing where repeated assembly cycles demand durable threaded components. The black-oxide surface treatment provides essential corrosion protection in manufacturing facilities with coolants or environmental exposure.
Specification Summary & Compliance
Manufactured to DIN 939 specifications with Class 2A thread fit tolerance for precise engagement. Features 1/2"-13 unified threading on both ends with 1/2" thread length per end and 1 1/2" overall length. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, meeting international standards for industrial fastener applications.
