Professional Applications & Engineering Value

These black-oxide steel setup studs deliver critical engineering advantages in precision manufacturing environments. The 1/2"-13 threading on both ends with varying thread lengths (2½" and ¾") provides flexible mounting solutions for jigs, fixtures, and machine tool setups. The Class 2A thread fit ensures consistent engagement while minimizing cross-threading risks during frequent adjustments. Meeting DIN 939 specifications, these studs maintain dimensional stability in high-vibration applications, while the 125,000 psi tensile strength prevents elongation under load. The black-oxide surface treatment extends service life in industrial atmospheres, making these setup studs ideal for CNC machining centers, assembly fixtures, and precision measurement equipment where repeatability and corrosion resistance are paramount.
