Professional Applications & Engineering Value

This 18-8 stainless steel shoulder screw is engineered to address common industrial challenges such as misalignment, component slippage, and corrosion-induced failure. The precise shoulder fit with minimal tolerances ensures accurate alignment in assemblies, reducing wear on mating parts and extending equipment life. Its hex socket drive allows for high-torque installation in confined spaces, while the coarse UNC thread and Class 2A fit provide quick, secure fastening that resists loosening under vibration. Ideal for use in machinery, automotive fixtures, and electronic enclosures, the passivated finish enhances corrosion resistance, making it a reliable choice for demanding environments where durability and precision are critical.

Specification Summary & Compliance

The screw adheres to UNC thread standards with a Class 2A thread fit for consistent performance. Shoulder dimensions include a diameter of 5/32" (tolerance: -0.001" to 0") and length of 1/4" (tolerance: 0" to 0.002"), ensuring precise assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for industrial applications with strict environmental and safety requirements.
