Professional Applications & Engineering Value
These DIN 939 setup studs deliver critical engineering solutions for precision machinery alignment, mold setting, and fixture applications where repeated assembly/disassembly is required. The black-oxide steel construction provides superior corrosion protection in manufacturing environments while maintaining dimensional stability. The 3/4"-10 threading with Class 2A fit ensures precise engagement in threaded holes without galling or seizing, significantly reducing maintenance downtime. With 2" thread lengths on both ends, these studs offer flexible installation options for temporary setups or permanent fixtures across automotive, aerospace, and heavy equipment industries where 125,000 psi tensile strength is essential for safety-critical connections.
Specification Summary & Compliance
Manufactured to DIN 939 specifications with Class 2A thread fit tolerance for precise engagement. The studs feature 3/4"-10 unified threading on both ends with 2" thread lengths (A and B) and 5½" total length. Mechanical properties include minimum 125,000 psi tensile strength and Rockwell C22 hardness. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance.
