Professional Applications & Engineering Value

This 3/4"-10 UNC shoulder screw is engineered to address critical challenges in precision machinery and industrial assembly. Made from 18-8 stainless steel with a black oxide finish, it resists corrosion and extends service life in demanding conditions. The socket head design with a knurled texture ensures secure handling, while the 2" shoulder provides stable support for rotating components like bearings and pulleys, minimizing misalignment and wear. With a Rockwell B55 hardness and high tensile strength, it withstands heavy loads and vibrations, making it ideal for automotive, aerospace, and manufacturing equipment where reliability is paramount.

Specification Summary & Compliance

This shoulder screw features Class 2A thread fit with UNC coarse threads for consistent performance. Dimensions include a 3/4"-10 thread size, 1" head diameter, and 2" shoulder length with tight tolerances (e.g., shoulder diameter tolerance of -0.004" to -0.002"). It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and adherence to industry standards for quality and reliability.
