Professional Applications & Engineering Value

This 6061 aluminum shoulder screw delivers critical engineering solutions where precision alignment and weight reduction are paramount. The Class 3A UNC thread with coarse spacing prevents cross-threading during high-speed assembly while maintaining vibration resistance in machinery, robotics, and automation equipment. The knurled socket head combined with hex drive ensures secure tool engagement, reducing installation errors in confined spaces. The precisely machined 3/16" shoulder diameter with minimal tolerance variation serves as reliable bearing surfaces in pulleys, gears, and rotating assemblies, eliminating the need for additional bushings. With 40,000 PSI tensile strength, it provides durable performance in industrial applications where corrosion resistance and electrical conductivity are advantageous.
