• Easy installation and removal with 3/32" hex drive, compatible with standard tools for efficient maintenance
• Secure component positioning through cup tip design, providing concentrated contact pressure without damaging surfaces
• Space-saving headless construction ideal for applications with limited clearance while maintaining full fastening strength
• Wide compatibility with UNC coarse threading, suitable for most industrial equipment and assembly requirements

Professional Applications & Engineering Value

This 10-24 UNC set screw delivers critical engineering solutions for industrial assembly challenges. The black-oxide alloy steel construction provides essential corrosion protection in manufacturing environments where moisture and chemicals are present. With Rockwell C45 hardness, it maintains dimensional stability under sustained vibration, preventing loosening in machinery, motor mounts, and precision equipment. The cup tip design concentrates clamping force on a small surface area, securely positioning gears, pulleys, and collars without slippage. The headless configuration and 3/32" hex drive enable installation in confined spaces where traditional fasteners cannot fit, while the coarse UNC threading ensures rapid assembly in production lines. These features make it indispensable for maintaining alignment and preventing relative motion in rotating assemblies across automotive, aerospace, and heavy equipment sectors.

Specification Summary & Compliance

This set screw features precision 10-24 UNC coarse threads with Class 3A fit for superior dimensional accuracy and engagement. Manufactured to ASME B18.3 specifications (ASTM F912) ensuring consistent quality and performance. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances. The black-oxide surface treatment provides additional corrosion protection while maintaining the mechanical properties of the underlying alloy steel material.
