Professional Applications & Engineering Value
This 316 stainless steel shoulder screw is engineered to address critical challenges in precision assemblies, such as maintaining exact part alignment and resisting chemical exposure. The ultra-low socket head with a hex drive allows for secure fastening in tight spaces, common in electronics, machinery, and optical devices. Its 2-56 UNC coarse thread and Class 2A fit ensure rapid, reliable installation without cross-threading, reducing assembly time and errors. The precise shoulder acts as a pivot or spacer, minimizing wear and vibration in moving parts. Ideal for industrial applications requiring high strength and corrosion resistance, this screw delivers consistent performance in demanding conditions, from marine to chemical processing equipment.
Specification Summary & Compliance
This shoulder screw adheres to UNC thread standards with a Class 2A fit for consistent thread engagement. Dimensions include a shoulder diameter of 3/32" (tolerance: -0.001" to 0") and length of 3/16" (tolerance: 0" to 0.002"), ensuring precise assembly. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting environmentally responsible manufacturing and use in regulated industries.
