S-90281A636 3/8"-16 x 3" DIN 939 Setup Studs

Key Features & Benefits at a Glance

• Enhanced corrosion resistance through black-oxide steel coating, extending component life in demanding industrial environments
• Precise thread engagement with Class 2A thread fit ensuring reliable fastening and reduced assembly time
• High tensile strength of 125,000 psi provides exceptional load-bearing capacity for critical setups
• Double-ended threading enables versatile mounting options and simplified installation in confined spaces
• Standardized dimensions per DIN 939 ensure consistent performance and interchangeability across equipment
• Regulatory compliance with RoHS 3 and REACH eliminates supply chain restrictions in global markets
• Optimized hardness at Rockwell C22 maintains structural integrity under repeated torque applications

Professional Applications & Engineering Value

These black-oxide steel setup studs address critical alignment challenges in precision machining and fixture assembly. The 3/8"-16 threading on both ends allows simultaneous attachment to machine beds and workholding devices, eliminating misalignment issues during production runs. With 1" threaded sections on each end, engineers achieve optimal clamp distribution while the black-oxide surface treatment resists coolant degradation and oxidation in manufacturing environments. The DIN 939 compliance guarantees dimensional stability for international tooling systems, making these setup studs ideal for CNC machining centers, jig boring applications, and modular fixture plates where repetitive accuracy is paramount.

Specification Summary & Compliance

Manufactured to DIN 939 standards with Class 2A thread fit tolerances for precise engagement. The 3" length with balanced threading configuration maintains structural integrity under 125,000 psi tensile loads. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance.
