- Guaranteed compliance and reliability meeting ASME B18.3 standards, RoHS 3, and REACH for global industrial use.
Professional Applications & Engineering Value
This 18-8 Stainless Steel shoulder screw is engineered to address critical alignment and rotational requirements in precision industrial applications. The 3/8" shoulder length and controlled diameter tolerance provide an exact locating surface for components like bearings, gears, and linkages, minimizing misalignment and wear. The 5/16"-24 UNF fine thread with a Class 3A fit ensures tight, secure fastening in assemblies subject to vibration, while the hex socket drive and knurled head facilitate efficient installation in confined spaces. Its high tensile and shear strength makes it suitable for demanding machinery, automation systems, and tooling fixtures, offering long-term reliability and reduced maintenance.
Specification Summary & Compliance
This shoulder screw adheres to strict dimensional standards, including a Class 3A thread fit for precision and a shoulder diameter tolerance of -0.004" to -0.002". It conforms to ASME B18.3 specifications and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity for industrial use.
