Professional Applications & Engineering Value
This 18-8 Stainless Steel shoulder screw is engineered to solve critical alignment and durability challenges in demanding industrial applications. Its precision shoulder with minimal diameter and length tolerances ensures exact component positioning, reducing vibration and wear in machinery, pivots, and rotating assemblies. The 3/8"-16 UNC coarse thread and Class 2A thread fit provide strong, reliable fastening, while the 1/4" hex drive allows for efficient installation in confined spaces. The passivated finish on the stainless steel significantly enhances corrosion resistance, making this shoulder screw a robust choice for automotive, aerospace, and manufacturing equipment where 70,000 psi tensile strength and long-term reliability are non-negotiable.
Specification Summary & Compliance
This shoulder screw adheres to inch system measurements with a Class 2A thread fit for the 3/8"-16 UNC coarse thread. The shoulder features a precise diameter tolerance of -0.001" to 0" and a length tolerance of 0" to 0.002". It is manufactured from 18-8 Stainless Steel with a passivated finish and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
