Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision machinery, automation systems, and rotating assemblies. The 3" shoulder length and 1/2" shoulder diameter provide a stable bearing surface that prevents misalignment and reduces wear on moving parts. The coarse 3/8"-16 UNC thread with Class 3A fit ensures secure fastening even under high vibration, while the hex socket drive and knurled head facilitate quick assembly in confined spaces. Ideal for industrial applications requiring corrosion resistance and high tensile strength, this component delivers reliable performance in conveyor systems, pivoting mechanisms, and precision instruments where dimensional accuracy is paramount.
Specification Summary & Compliance
This shoulder screw maintains tight tolerances with shoulder diameter tolerance of -0.004" to -0.002" and shoulder length tolerance of -0.005" to 0.005". Thread specifications include 3/8"-16 UNC coarse thread with Class 3A fit for precision engagement. Manufacturing complies with ASME B18.3 specifications, and the product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to international environmental and safety standards.
