Professional Applications & Engineering Value

This 6-32 UNC shoulder screw is engineered to solve critical challenges in precision assembly and machinery. The 316 stainless steel material provides exceptional resistance to corrosion and chemicals, making it suitable for applications in chemical processing, marine equipment, and food machinery where exposure to corrosive elements is a concern. The black oxide finish not only adds an extra layer of protection against rust but also reduces galling during installation. With its Class 3A thread fit and coarse UNC thread, it ensures quick, secure fastening in high-vibration environments, preventing loosening over time. The knurled socket head design enhances grip for efficient torque application, reducing assembly time and improving worker safety. This screw is ideal for use in pivots, linkages, and rotating assemblies where the shoulder acts as a precision bearing surface or spacer, maintaining alignment and reducing wear on components.

Specification Summary & Compliance

This shoulder screw adheres to precise dimensional standards, including a Class 3A thread fit for high-accuracy assemblies and UNC coarse threads for robust performance. The shoulder diameter tolerance is maintained between -0.004" to -0.002", and the shoulder length tolerance from -0.005" to 0.005", ensuring consistent quality. It is manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious industrial applications without hazardous substances.
