Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address common industrial challenges such as misalignment, corrosion, and high-stress fatigue. The 3/4"-10 UNC coarse thread and Class 3A fit ensure rapid, secure fastening in machinery, automotive, and aerospace components, reducing downtime. The knurled socket head with a 1/2" hex drive provides excellent torque transmission, preventing stripping in high-vibration environments. With a Rockwell B79 hardness and 70,000 psi tensile strength, it supports heavy-duty applications like pivots, shafts, and guides, offering long-term reliability and minimal maintenance in corrosive or demanding settings.
Specification Summary & Compliance
This shoulder screw features a 3/4"-10 UNC thread with Class 3A precision, ensuring tight tolerances for reliable performance. The shoulder diameter is 7/8" with a tolerance of -0.004" to -0.002", and the shoulder length is 3 1/2" with a tolerance of -0.005" to 0.005". Manufactured to ASME B18.3 specifications, it complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, supporting safe and environmentally responsible industrial use.
