Professional Applications & Engineering Value

These precision shoulder screws solve critical alignment challenges in mechanical systems where components must rotate or pivot accurately on the 1/4" shoulder diameter. The alloy steel construction combined with black oxide finish provides excellent wear resistance in high-friction applications such as rotating shafts, bearing retainers, and linkage assemblies. The UNC coarse thread with Class 2A fit ensures reliable engagement in both metallic and non-metallic materials, while the hex socket drive enables secure installation in space-constrained environments. These shoulder screws deliver consistent performance in automation equipment, precision machinery, and industrial fixtures where dimensional stability under load is paramount.

Specification Summary & Compliance

Manufactured to exacting standards with Class 2A thread fit and precise shoulder tolerances (-0.001" to 0" diameter, 0" to 0.002" length). Features 10-24 UNC coarse threads with right-hand direction and 3/8" thread length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications.
