• Precise thread engagement with UNC Class 3A fit, delivering reliable fastening and vibration resistance in machinery.
• Easy installation in tight spaces using the 1/16" hex drive and headless design, ideal for compact assemblies.
• Broad industrial compliance meeting ASME B18.3 standards, RoHS 3, and REACH for global quality assurance.
• Optimized for coarse thread applications with right-hand UNC threading, enabling quick assembly and disassembly.

Professional Applications & Engineering Value

This 5-40 UNC set screw is engineered to solve critical alignment and slippage issues in precision machinery, automotive components, and electronic enclosures. The Black-Oxide alloy steel construction combats rust and wear, while the 90° cone point bites securely into shafts and collars, preventing rotational movement under high torque. Its headless design and 1/16" hex drive allow flush mounting in confined spaces, reducing assembly bulk. With coarse thread spacing and Class 3A thread fit, it ensures rapid installation and consistent clamping force, making it a reliable choice for industrial set screws in maintenance and production lines.

Specification Summary & Compliance

This set screw adheres to ASME B18.3 specifications with a UNC Class 3A thread fit for precise dimensional accuracy. It is manufactured from alloy steel with a Black-Oxide surface treatment and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use in global markets.
