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 UNC coarse thread and Class 3A fit provide secure fastening in machinery, electronics, and automotive systems, reducing downtime from loose connections. The knurled head and hex socket drive facilitate quick tool engagement, even in confined spaces. With high tensile and shear strength, it supports heavy loads and dynamic stresses, making it ideal for pivots, spacers, and rotating assemblies in corrosive or high-moisture environments.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A precision fit for tight tolerances. Key dimensions include a 5/32" head diameter, 1/8" thread length, and shoulder diameter tolerance of -0.004" to -0.002". It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial applications requiring reliable, long-lasting fastening solutions.
