Professional Applications & Engineering Value

This M20 metric set screw is engineered to solve critical fastening challenges in industrial machinery, automotive components, and precision equipment. The alloy steel construction and Rockwell C45 hardness provide exceptional resistance to shear forces and fatigue, making it ideal for securing gears, pulleys, and collars on rotating shafts. The extended tip and coarse 2.5mm pitch thread work in tandem to ensure maximum bite and holding power, preventing component slippage even under high torque and vibrational stress. Its headless design with a hex drive allows for a clean, unobtrusive installation in space-constrained assemblies, streamlining maintenance and reducing the risk of snagging. This set screw delivers reliable performance in demanding environments where failure is not an option.
