Professional Applications & Engineering Value
This black-oxide steel setup stud is engineered to address critical challenges in industrial assembly, such as misalignment and component fatigue. Its 1/2"-13 threading on both ends and adherence to DIN 939 ensure precise fitment in machinery setup, jig and fixture construction, and alignment systems. The black-oxide surface treatment provides a protective layer against rust and wear, extending component life in demanding environments like automotive manufacturing or heavy equipment. With a minimum tensile strength of 125,000 psi and Rockwell C22 hardness, it resists shear forces and repeated stress, reducing maintenance downtime and enhancing operational reliability for B2B clients in precision engineering sectors.
Specification Summary & Compliance
This stud meets Class 2A thread fit tolerances for consistent engagement, manufactured in accordance with DIN 939 specifications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and health standards. Dimensions include a 4 1/2" length with 1 1/2" thread lengths on both ends, supporting reliable performance in industrial applications.
