Professional Applications & Engineering Value

This 18-8 Stainless Steel Socket Head Cap Screw delivers critical performance advantages for industrial applications where corrosion resistance and high tensile strength are paramount. The UNC coarse thread configuration enables rapid assembly in machinery, equipment frames, and structural components while minimizing thread damage during installation. With its 3/16" hex drive and standard socket profile, engineers benefit from superior torque transmission in confined spaces where wrench clearance is limited. The partially threaded design provides optimal clamping force distribution, making it ideal for precision assemblies in manufacturing, automotive, and aerospace sectors. These socket head cap screws maintain dimensional stability under heavy loads, solving common fastening failures in high-vibration environments.

Specification Summary & Compliance

Manufactured to exacting ASME B18.3 standards with Class 3A thread fit for superior dimensional accuracy and interchangeability. The UNC 1/4"-20 coarse thread specification ensures reliable performance in industrial fastening applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe usage across global markets. The 3-1/2" length with 1" minimum thread length provides consistent engagement depth for secure fastening connections.
