Professional Applications & Engineering Value
These 5/16"-18 threaded setup studs deliver critical precision in jig and fixture manufacturing, where black-oxide steel construction provides essential corrosion protection in machining environments. The double-ended threading with Class 2A fit eliminates alignment issues during tooling changes, while the 125,000 psi tensile strength ensures stability in high-vibration applications like CNC machining centers. Engineered to DIN 939 specifications, these studs maintain dimensional accuracy across production runs, reducing downtime in automotive assembly lines and industrial mold setups. The combination of 3/4" thread length on both ends with Rockwell C22 hardness creates a durable interface that withstands repeated clamping cycles without deformation.
Specification Summary & Compliance
Manufactured to Class 2A thread fit tolerances with 5/16"-18 unified thread form and 3/4" thread length on both ends. Complies with DIN 939 manufacturing specifications while meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives. Mechanical properties include 125,000 psi minimum tensile strength and Rockwell C22 minimum hardness for consistent performance across industrial applications.
