Professional Applications & Engineering Value

This 1/2"-13 UNC thread shoulder screw is engineered for precision alignment and load-bearing in demanding industrial settings. Made from 18-8 stainless steel, it resists corrosion and oxidation, making it suitable for machinery, automotive assemblies, and electronic enclosures exposed to moisture or chemicals. The coarse thread spacing and Class 3A thread fit enable quick assembly and reduce the risk of cross-threading, while the knurled head and 1/4" hex drive facilitate secure tool engagement in confined spaces. Its high tensile and shear strength ensures dependable performance in pivots, rotating shafts, and other high-stress applications, minimizing downtime and maintenance costs.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A thread fit for precise tolerance. Dimensions include a shoulder diameter of 1/2" with tight tolerances (e.g., -0.004" to -0.002") and a thread length of 5/8". It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
