Professional Applications & Engineering Value

This precision shoulder screw is engineered to address critical alignment and stability challenges in industrial assemblies. The 18-8 stainless steel material provides excellent corrosion resistance, making it suitable for applications in electronics, machinery, and medical devices where exposure to moisture or chemicals is a concern. The fine UNF thread (0-80) and Class 2A fit ensure reliable thread engagement in tight spaces, reducing the risk of stripping and improving load distribution. With a precisely machined shoulder diameter of 0.0615" and minimal tolerances, it enables exact component positioning, minimizing misalignment and wear in pivots, bearings, or guides. This socket head shoulder screw is ideal for B2B sectors requiring repeatable precision and compliance with environmental standards like RoHS and REACH.
