Professional Applications & Engineering Value
These black-oxide steel setup studs solve critical alignment and mounting challenges in industrial machinery assembly. The 3/4"-10 threading with Class 2A fit provides precise component positioning while resisting vibrational loosening in high-stress environments. The dual-threaded configuration enables efficient temporary fixturing during manufacturing processes and permanent installations in heavy equipment. The 125,000 psi tensile strength ensures reliable performance in jig and fixture applications where repeated loading cycles would compromise inferior fasteners. DIN 939 compliance guarantees dimensional consistency for international engineering projects requiring standardized metric-equivalent components.
Specification Summary & Compliance
Manufactured to DIN 939 standards with Class 2A thread fit tolerances ensuring precision engagement. The 3-1/2" length with balanced 1-1/4" thread lengths on both ends maintains dimensional accuracy for repetitive assembly operations. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest substance restriction requirements for industrial components.
