Professional Applications & Engineering Value
These 7/8"-9 threaded setup studs provide critical solutions for precision assembly challenges where alignment accuracy and structural integrity are paramount. The black-oxide steel construction offers enhanced corrosion protection in manufacturing environments exposed to moisture and chemicals, while the double-ended threading with Class 2A fit ensures precise mating with corresponding components. Engineered to DIN 939 standards, these 5-inch studs deliver reliable performance in jig and fixture applications, machinery setup, and precision tooling systems where 125,000 psi tensile strength and Rockwell C22 hardness prevent deformation under heavy loads. The balanced thread length distribution (2" on each end) facilitates secure mounting in complex assembly configurations.
Specification Summary & Compliance
These setup studs feature precise Class 2A thread fit with 7/8"-9 threading on both ends and 2" thread lengths per end. Manufactured from high-strength steel with black-oxide surface treatment, they meet DIN 939 specifications for dimensional accuracy and performance. The studs demonstrate compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current international substance restriction requirements for industrial components.
