Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and tooling jigs. The 10-32 UNF fine thread and Class 3A thread fit provide exceptional resistance to loosening under vibration, a common failure point in dynamic industrial settings. The knurled head and hex socket drive facilitate quick assembly and disassembly, reducing maintenance downtime. With a robust 70,000 psi tensile strength and a precisely machined shoulder, this component ensures accurate axial positioning and rotational stability for gears, pulleys, and linkages, enhancing overall system longevity and performance in industrial applications.
Specification Summary & Compliance
This shoulder screw adheres to ASME B18.3 specifications, featuring a Class 3A thread fit for high precision. Key dimensional attributes include a shoulder diameter of 1/4" (tolerance: -0.004" to -0.002") and shoulder length of 1 5/8" (tolerance: -0.005" to 0.005"). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for global industrial use.
