Professional Applications & Engineering Value
These DIN 939 setup studs are engineered to address common challenges in precision machining and assembly, such as misalignment and component slippage. The 3/8"-16 threading on both ends with a Class 2A thread fit ensures quick, secure fastening in jigs, fixtures, and tooling setups, reducing downtime. Made from Black-Oxide Steel, they offer excellent resistance to rust and wear, which is critical in environments exposed to coolants or varying temperatures. The high tensile strength of 125,000 psi and consistent hardness provide reliable performance in high-stress applications, from CNC machining to automotive assembly, ensuring long-term stability and reducing the need for frequent replacements.
Specification Summary & Compliance
This setup stud features a 5 1/2" length with 1 1/4" thread length on each end, adhering to Class 2A thread fit tolerances for precise engagement. It meets the DIN 939 standard for dimensional consistency and is manufactured from high-strength steel with a black-oxide surface treatment. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for global industrial use.
