Professional Applications & Engineering Value

This 6-32 UNC shoulder screw is engineered to address critical alignment and durability challenges in precision assemblies. The 18-8 Stainless Steel material offers inherent corrosion resistance, making it suitable for machinery, electronics, and automotive components exposed to moisture or chemicals. The precise shoulder with tight diameter and length tolerances acts as a reliable locating dowel, minimizing part shift and wear in rotating mechanisms. Combined with a low socket head and coarse UNC threads, it streamlines installation in high-volume production while the 70,000 psi tensile strength ensures joint integrity under dynamic loads. Ideal for securing bearings, gears, and linkages where exact positioning and long-term reliability are paramount.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. Shoulder diameter is maintained at 5/32" with a tolerance of -0.001" to 0", and shoulder length is 5/16" with a 0" to 0.002" tolerance, ensuring precision-grade performance. The product is manufactured to comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for restricted substance-controlled applications.
