Professional Applications & Engineering Value

This 3/8"-16 UNC set screw delivers critical engineering solutions for industrial assembly challenges. The Black-Oxide 12L14 Steel construction provides essential corrosion protection while maintaining machinability, ideal for automated production environments. The innovative removable swivel tip technology addresses alignment issues in precision machinery, allowing ±10° adjustment to compensate for component tolerances without compromising clamping force. The headless design with 3/16" hex drive enables installation in confined spaces while transmitting maximum torque for secure shaft collars, gear hubs, and pulley systems. These industrial set screws prevent relative motion between rotating components through their coarse UNC threads, making them particularly valuable in vibration-prone applications across manufacturing, automotive, and heavy equipment sectors.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit for consistent performance across production runs. Features 3/8"-16 UNC coarse threads with right-hand direction following established industrial specifications. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial supply chains. The Black-Oxide surface treatment on 12L14 steel provides additional corrosion protection while maintaining the material's mechanical properties for reliable fastening performance.
