Professional Applications & Engineering Value
This precision shoulder screw is engineered to address critical alignment and durability challenges in industrial machinery, automation systems, and precision instruments. The 18-8 stainless steel material combined with a passivated finish resists oxidation and chemical exposure, extending service life in moist or corrosive settings. Its 3/32" shoulder diameter with minimal tolerance variation ensures exact positioning for bearings, gears, or linkages, reducing vibration and misalignment issues. The 2-56 UNC coarse thread and Class 2A fit facilitate quick assembly while maintaining strong holding power, making it ideal for right-hand thread applications in electronics, automotive, and aerospace components where reliability is paramount.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. The shoulder features precise diameter and length tolerances (e.g., shoulder diameter: -0.001" to 0", shoulder length: 0" to 0.002") to meet rigorous engineering requirements. It conforms to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring compliance with international environmental and safety standards for industrial use.
