Professional Applications & Engineering Value

This 18-8 stainless steel shoulder screw is engineered to address common industrial challenges such as misalignment and corrosion in machinery. The 3/8"-16 UNC coarse threads and external hex drive facilitate quick assembly in high-vibration settings, while the 2-1/4" shoulder length provides a stable pivot or spacer in applications like rotating assemblies, conveyor systems, and automotive components. Its high tensile and shear strength ensures it can withstand heavy loads without failure, making it a reliable choice for precision shoulder bolt uses in manufacturing and equipment maintenance.

Specification Summary & Compliance

The screw features a Class 2A thread fit for standard UNC threading, with shoulder diameter tolerance of -0.004" to 0" and shoulder length tolerance of -0.005" to 0.005" to ensure dimensional accuracy. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications without hazardous substances.
