Professional Applications & Engineering Value

This 316 Stainless Steel Shoulder Screw is engineered to address critical challenges in precision machinery and industrial assembly. The Black Oxide finish not only enhances corrosion resistance but also minimizes friction and galling in high-movement applications. Featuring a 2" shoulder length with tight tolerances, it provides a stable pivot or spacer, reducing misalignment and wear on connected components. The Class 3A thread fit and UNC coarse threads ensure secure fastening in vibrating environments, while the knurled socket head with a hex drive allows for efficient installation in confined spaces. Ideal for use in robotics, automotive systems, and conveyor equipment, this screw delivers reliable performance where high tensile strength and dimensional accuracy are paramount.

Specification Summary & Compliance

This shoulder screw adheres to precise dimensional standards, including a Class 3A thread fit for superior accuracy and a shoulder diameter tolerance of -0.004" to -0.002". It is manufactured in compliance with ASME B18.3 specifications and meets environmental regulations such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring safety and sustainability in industrial applications.
