Professional Applications & Engineering Value
These 5/16"-18 threaded setup studs deliver critical engineering solutions for precision machinery assembly and industrial equipment manufacturing. The black-oxide steel construction provides superior corrosion protection in harsh operating conditions, while the dual-end threading with specific 1" and 1/2" thread lengths enables precise component positioning and alignment in jigs, fixtures, and automated systems. Engineered to DIN 939 specifications, these studs maintain consistent performance in high-vibration environments where Class 2A thread fit ensures reliable engagement without galling or cross-threading. The combination of 125,000 psi tensile strength and Rockwell C22 hardness makes them ideal for permanent installations requiring dimensional stability under continuous mechanical stress.
Specification Summary & Compliance
Manufactured to DIN 939 standards with Class 2A thread fit precision, these setup studs feature 5/16"-18 unified threads with dual-end threading (1" and 1/2" thread lengths). The black-oxide steel construction delivers minimum 125,000 psi tensile strength and Rockwell C22 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and global market acceptance for industrial applications.
