- High tensile strength of 125,000 psi ensures reliable performance under heavy loads and prevents premature failure.
- Precision Class 2A thread fit on both ends for easy, secure installation and consistent alignment in assembly setups.
- DIN 939 compliance guarantees standardized dimensions and interchangeability in European machinery and equipment.
- Rockwell C22 hardness provides excellent wear resistance, maintaining thread integrity through repeated use.
- RoHS 3 and REACH compliance ensures environmental safety and regulatory adherence for global supply chains.
- Dual-end threading simplifies fixturing and setup processes, reducing assembly time and labor costs.
Professional Applications & Engineering Value
These black-oxide steel setup studs are engineered to address common challenges in industrial fixturing, such as alignment accuracy and durability under cyclic loading. The 1/2"-13 threading on both ends with Class 2A fit ensures precise engagement in jigs, molds, and machinery setups, minimizing play and vibration. Made from high-strength steel with a protective black-oxide coating, they resist rust and wear in harsh conditions like manufacturing floors or automotive assembly lines. The 125,000 psi tensile strength and Rockwell C22 hardness provide reliable clamping force and longevity, reducing downtime for maintenance. Ideal for CNC machining fixtures, welding jigs, and precision tooling, these DIN 939 compliant studs deliver consistent performance, enhancing productivity and reducing rework in B2B industrial applications.
Specification Summary & Compliance
These setup studs feature a 5 1/2" length with 1 1/2" thread length on each end, manufactured to Class 2A thread fit tolerances for precise assembly. They conform to DIN 939 standards for dimensional consistency and meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring adherence to environmental and safety regulations in industrial use.
