Professional Applications & Engineering Value

This black-oxide alloy steel set screw addresses critical industrial fastening challenges where vibration resistance, corrosion protection, and precise component alignment are paramount. The permanent swivel tip design distributes clamping force evenly across contact surfaces, preventing localized stress concentrations that can lead to component deformation or failure. With UNC coarse threads and Class 2A thread fit, installation efficiency is maximized while maintaining secure fastening in high-vibration environments common to machinery, automotive assemblies, and heavy equipment. The headless configuration with hex drive enables flush mounting in confined spaces where traditional fastener heads would interfere with adjacent components or moving parts.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerance for consistent performance across applications. Features 5/8"-11 UNC coarse threads with right-hand orientation and 5/16" hex drive compatibility. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial supply chains. The alloy steel construction with Rockwell C39 hardness provides reliable mechanical properties for demanding fastening requirements.
