Professional Applications & Engineering Value
This 316 Stainless Steel Shoulder Screw is engineered to address common industrial challenges such as component misalignment, corrosion-induced failure, and assembly inefficiency. The 10-32 UNF fine thread and Class 3A fit provide vibration resistance and precise engagement in machinery, automation systems, and precision instruments. The knurled socket head improves handling and torque application, reducing installation time. With a 1/4" shoulder length and diameter, it acts as a reliable pivot, spacer, or axle in assemblies, while the high tensile strength and corrosion resistance of 316 SS ensure durability in demanding environments like marine, chemical processing, and food equipment.
Specification Summary & Compliance
This shoulder screw features a 10-32 UNF fine thread with a Class 3A fit for high precision. Key dimensions include a 1/4" shoulder diameter (tolerance: -0.004" to -0.002") and 1/4" shoulder length (tolerance: -0.005" to 0.005"). It is manufactured to ASME B18.3 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
