Professional Applications & Engineering Value

This 6061 aluminum shoulder screw delivers exceptional engineering value in precision mechanical assemblies where weight reduction, corrosion resistance, and dimensional accuracy are critical. The 8-32 UNC coarse thread with Class 3A fit ensures rapid, secure fastening in aluminum components and plastic housings, while the 3/16" shoulder length provides exact spacing for gears, pulleys, and rotating elements. The hex drive socket head with knurled texture prevents tool slippage during torque application, maintaining installation integrity in automated assembly lines. Ideal for robotics, precision instrumentation, and light-duty machinery, this shoulder screw combines the strength of 40,000 psi tensile rating with the weight advantages of aluminum construction, solving vibration-induced loosening and alignment challenges in dynamic applications.
