Professional Applications & Engineering Value

This 3/8"-16 UNC shoulder screw is engineered to address critical alignment and stability challenges in industrial applications. The 18-8 stainless steel material provides outstanding corrosion resistance, making it suitable for machinery exposed to moisture, chemicals, or outdoor elements. The 2" shoulder length with precise tolerances acts as a reliable alignment pin, preventing rotational movement and ensuring accurate component positioning in assemblies like pivots, linkages, and rotating shafts. The coarse thread and external hex head facilitate quick installation, while the Class 2A thread fit and high tensile strength deliver secure, vibration-resistant connections in equipment requiring repeated adjustments or heavy loads.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. Key specifications include a 3/8"-16 thread size, 2" shoulder length (±0.005" tolerance), and 1/2" shoulder diameter (-0.004" to 0" tolerance). It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring environmental safety and quality in industrial use.
