Professional Applications & Engineering Value
This precision shoulder screw is engineered to solve critical alignment and wear issues in demanding applications. The 18-8 stainless steel construction, enhanced by a passivated finish, provides excellent resistance to corrosion and oxidation, extending service life in machinery, automation systems, and conveyor equipment. The UNC coarse thread and Class 2A thread fit ensure quick, reliable fastening, while the precisely machined shoulder diameter and length act as a pivot or spacer, reducing wear on moving parts and maintaining alignment in assemblies like bearings, gears, and linkages. The hex socket head allows for high-torque installation in confined spaces, making it a versatile choice for OEMs and maintenance teams seeking durability and precision in industrial shoulder screws.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. Key specifications include a shoulder diameter of 3/8" with a tight tolerance and a shoulder length of 1/2". The product is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
