Professional Applications & Engineering Value
This 8-32 UNC shoulder screw is engineered to address common industrial challenges such as component misalignment and vibration-induced loosening. The precise shoulder diameter of 3/16" with minimal tolerances ensures exact positioning in assemblies, reducing wear and improving operational accuracy. Made from 18-8 stainless steel, it offers excellent corrosion resistance and strength, suitable for applications in automotive, aerospace, and machinery where reliability is critical. The integrated nylon patch thread locker provides a permanent locking mechanism, eliminating the need for additional adhesives and maintaining integrity under thermal cycling from -70° to 250°F. This combination of vibration-resistant features and robust material properties delivers long-term performance in demanding environments.
Specification Summary & Compliance
This shoulder screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent engagement. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. Manufacturing includes precise shoulder dimensions (diameter: 3/16" with -0.001" to 0" tolerance; length: 5/16" with 0" to 0.002" tolerance) and a hex drive size of 3/32" for standardized tool compatibility.
