Professional Applications & Engineering Value
This precision shoulder screw is engineered from alloy steel with a black oxide finish to address common industrial challenges such as misalignment and corrosion. The 1/2" shoulder diameter and precise fit provide stable bearing surfaces in machinery, automotive, and automation systems, reducing friction and component wear. With 3/8"-16 UNC coarse threading and right-hand thread direction, it ensures fast, secure fastening in high-vibration environments. The socket head design allows for efficient torque application, making it ideal for applications requiring reliable industrial fasteners that maintain integrity under 140,000 psi tensile strength.
Specification Summary & Compliance
This shoulder screw features Class 2A thread fit and UNC thread standard for consistent dimensional accuracy, with shoulder diameter tolerance of -0.001" to 0" and shoulder length tolerance of 0" to 0.002". It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to environmental and safety standards in manufacturing and industrial use.
