Professional Applications & Engineering Value

This 6-32 UNC thread shoulder screw is engineered to address critical alignment and wear challenges in precision assemblies. The 18-8 stainless steel material offers excellent resistance to rust and chemical exposure, while the TiCN coating significantly reduces friction and wear in high-cycle applications like robotics, conveyor systems, and automated machinery. The precise shoulder fit with minimal tolerances ensures accurate component positioning, minimizing misalignment and reducing stress on adjacent parts. With a coarse thread design and right-hand direction, it facilitates quick installation in industrial fastening scenarios where vibration resistance and durability are paramount. Ideal for use in pivots, bearings, and linkages, this screw enhances operational reliability and reduces maintenance downtime.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent engagement. Dimensions include a thread diameter of 0.138", thread length of 3/16", shoulder diameter of 5/32" (tolerance: -0.002" to 0"), and shoulder length of 1/2" (tolerance: 0" to 0.003"), ensuring high precision. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, supporting safe and regulated use in various industrial sectors.
