Professional Applications & Engineering Value
This 6-32 UNC set screw delivers critical engineering solutions for industrial applications requiring permanent positioning and torque transmission. The black-oxide alloy steel construction provides enhanced corrosion protection while maintaining the Rockwell C45 hardness necessary for high-stress environments. The cup point tip creates permanent indentations in mating surfaces, preventing rotational slippage in pulleys, gears, and collars. The hex headless design allows flush mounting in confined spaces, while the Class 3A thread fit ensures precise engagement with minimal backlash. These industrial set screws are engineered to maintain positioning accuracy in manufacturing equipment, automotive assemblies, and machinery where vibration resistance is paramount.
Specification Summary & Compliance
This set screw features 6-32 UNC coarse threads with Class 3A precision tolerance for superior thread engagement. Manufacturing complies with ASME B18.3 standards (ASTM F912) ensuring dimensional consistency and performance reliability. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant regarding substance restrictions, making it suitable for global industrial applications with environmental regulatory requirements.
