Professional Applications & Engineering Value

This M10 set screw delivers exceptional engineering value through its optimized material and structural design. The alloy steel composition combined with Rockwell C45 hardness provides superior resistance to wear and deformation, solving common industrial challenges of component loosening under vibration and heavy loads. The cup point design creates concentrated pressure that securely bites into shafts, collars, and hubs, preventing rotational slippage in power transmission systems and precision machinery. The coarse thread with 1.5mm pitch ensures rapid installation and reliable holding in various materials, while the hex drive configuration allows for high torque application without stripping. These features make it ideal for industrial applications including gear assemblies, coupling connections, and precision equipment where secure positioning is critical to operational safety and performance longevity.
