Professional Applications & Engineering Value
This precision shoulder screw delivers exceptional engineering value in applications requiring exact component alignment and spacing. The 416 stainless steel construction provides excellent corrosion resistance while maintaining the Rockwell C26 hardness needed for repeated assembly cycles. The 3/16" shoulder length and precise diameter tolerance ensure components maintain proper positioning without additional spacers or bushings. The hex socket head allows for secure tightening in confined spaces, while the 8-32 UNC coarse thread and Class 2A thread fit provide reliable engagement in various materials. Ideal for machinery assemblies, precision instruments, and automated equipment where vibration resistance and dimensional accuracy are critical.
Specification Summary & Compliance
Manufactured to exacting standards with Class 2A thread fit and precise shoulder dimensions (3/16" diameter with -0.001" to 0" tolerance, 5/16" length with 0" to 0.002" tolerance). Thread specifications include 8-32 UNC coarse thread in right-hand direction. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for environmental safety. All measurements follow the inch system for compatibility with North American industrial standards.
