Professional Applications & Engineering Value
These Black-Oxide Steel Setup Studs are engineered to address common challenges in industrial assembly, such as misalignment and component fatigue. The 1"-8 threading on both ends with Class 2A thread fit ensures precise alignment in machinery setups, reducing installation time and minimizing the risk of cross-threading. Made from high-strength steel with a protective black-oxide finish, they resist corrosion in humid or abrasive conditions, making them ideal for CNC machines, automotive jigs, and heavy-duty fixtures. Their compliance with DIN 939 standards ensures reliability in European engineering projects, while the 125,000 psi tensile strength supports sustained performance in dynamic loads, preventing failures in critical applications.
Specification Summary & Compliance
This setup stud features a 4" length with 1 1/2" thread lengths on both ends and a Class 2A thread fit for precise tolerance per inch-based standards. It meets DIN 939 specifications for dimensional consistency and is manufactured from steel with a minimum Rockwell C22 hardness. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and health safety requirements in industrial supply chains.
