Professional Applications & Engineering Value
This precision shoulder screw is engineered to address common industrial challenges such as misalignment and component wear. Made from alloy steel with a black oxide finish, it offers excellent resistance to rust and abrasion, making it ideal for machinery assemblies, pivoting mechanisms, and high-stress environments. The 1/2" shoulder diameter provides a precise bearing surface, ensuring smooth rotational movement and reducing friction in applications like conveyor systems, automotive fixtures, and robotic arms. Its 3/8"-16 UNC coarse threads and Class 2A thread fit deliver reliable fastening, while the socket head design with a 1/4" hex drive allows for efficient installation in confined spaces, enhancing productivity and minimizing downtime in B2B operations.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety. Specifications include a shoulder diameter of 1/2" with tolerances from -0.001" to 0", and a shoulder length of 1" with tolerances from 0" to 0.002" for precise engineering applications.
