Professional Applications & Engineering Value

This Nylon 6/6 Plastic Shoulder Screw is engineered to address critical needs in precision assemblies where metal fasteners are unsuitable. Its non-conductive and corrosion-resistant properties make it perfect for electrical enclosures, machinery guards, and conveyor systems, eliminating galvanic corrosion risks. The 1 1/4" shoulder length with tight tolerances ensures accurate spacing and acts as a reliable axle or pivot in rotating mechanisms, reducing wear on moving parts. The 5/16"-18 UNC coarse thread and hex socket drive facilitate quick installation in plastic or soft materials, preventing stripping. Ideal for industries like packaging, automotive, and electronics, this screw provides a lightweight, durable RoHS compliant solution that withstands temperature fluctuations and demanding operational environments.

Specification Summary & Compliance

This shoulder screw adheres to UNC coarse thread standards with a Class 2A thread fit for consistent engagement. The shoulder diameter tolerance is -0.012" to -0.002" and length tolerance is -0.015" to 0.015", ensuring precision in assembly. Manufactured from Nylon 6/6 plastic, it is fully RoHS 3 (2015/863/EU) Compliant, meeting stringent environmental and safety regulations for industrial use.
