Professional Applications & Engineering Value

This black-oxide alloy steel set screw delivers critical engineering solutions for industrial applications where vibration resistance and permanent fastening are paramount. The extended tip design creates deeper engagement in mating components, significantly reducing the risk of loosening under dynamic loads. The square head configuration with external drive allows for high-torque installation without cam-out, making it ideal for machinery, heavy equipment, and manufacturing fixtures. The coarse UNC thread ensures rapid assembly in challenging materials while maintaining Class 2A thread fit precision. This combination addresses common industrial pain points including component slippage, fastener failure, and maintenance downtime, providing reliable performance in demanding environments from production machinery to structural assemblies.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2A thread fit tolerance and inch system measurements. The set screw features a 3/4"-10 UNC coarse thread configuration with right-hand orientation. Tip dimensions maintain tight tolerances with length variation of -0.005" to 0.005" and diameter tolerance of -0.013" to 0". The component fully complies with ASTM F912 specifications for set screws and meets environmental regulations including RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) requirements, ensuring both performance reliability and regulatory adherence for industrial applications.
