Professional Applications & Engineering Value
This 316 Stainless Steel shoulder screw is engineered to address common industrial challenges, such as component misalignment and corrosion-induced failure. Its UNC coarse threads and Class 3A thread fit deliver reliable fastening in high-vibration settings, reducing maintenance downtime. The knurled socket head and hex drive design facilitate quick assembly, while the precisely machined shoulder ensures accurate spacing in machinery like conveyor systems, automotive assemblies, and electronic enclosures. Made from corrosion-resistant 316 stainless steel, it performs reliably in moist or chemical-exposed environments, extending equipment lifespan and minimizing replacement costs.
Specification Summary & Compliance
This shoulder screw adheres to Class 3A thread fit tolerances for precise engagement, with UNC coarse threads (size 10-24) and a right-hand thread direction. The shoulder diameter is 1/4" with a tolerance of -0.004" to -0.002", and shoulder length is 5/16" with a tolerance of -0.005" to 0.005". It meets ASME B18.3 specifications for dimensional accuracy and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards.
