Professional Applications & Engineering Value

These black-oxide steel setup studs deliver critical engineering solutions for precision manufacturing and assembly operations. The 5/16"-18 threading on both ends with Class 2A fit provides superior alignment accuracy in jig and fixture applications, eliminating costly misalignment issues in CNC machining and production setups. The 4" length with differentiated thread zones (1½" and ½") offers versatile mounting options while maintaining structural integrity under repeated use. The black-oxide surface treatment creates a protective barrier against industrial contaminants and moderate corrosion, significantly extending component life in manufacturing environments. Engineered to DIN 939 standards, these studs ensure reliable performance in European and international equipment, making them ideal for global manufacturing operations requiring standardized components.

Specification Summary & Compliance

These setup studs feature 5/16"-18 UNC threads with Class 2A tolerance for precise fitment, manufactured to DIN 939 specifications for dimensional accuracy and performance consistency. The components maintain 125,000 psi minimum tensile strength and Rockwell C22 hardness throughout the entire stud length. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) adherence, ensuring restricted substance compliance for international industrial applications.
