• Generous 3/4" shoulder length allows for precise component alignment and spacing in machinery and fixtures.

Professional Applications & Engineering Value

This 18-8 stainless steel shoulder screw is engineered to address common industrial challenges such as misalignment, vibration loosening, and corrosion-induced failure. Its 1/4"-20 UNC coarse threads with Class 3A fit ensure secure fastening in high-stress environments, while the 3/4" shoulder length provides a stable pivot or bearing surface for rotating parts in assemblies like conveyor systems, robotics, and precision instruments. The knurled socket head and hex drive facilitate quick installation and removal, reducing downtime. Made from corrosion-resistant stainless steel, it withstands exposure to moisture and chemicals, making it ideal for industrial fasteners in automotive, aerospace, and manufacturing sectors where durability and reliability are paramount.

Specification Summary & Compliance

This shoulder screw adheres to UNC thread standards with a Class 3A fit for precise dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. The shoulder diameter tolerance is -0.004" to -0.002", and shoulder length tolerance is -0.005" to 0.005", supporting consistent performance in engineering applications.
