Professional Applications & Engineering Value

This M16 metric set screw is engineered to solve critical fastening challenges in heavy-duty industrial applications. The alloy steel material, hardened to Rockwell C45, provides superior resistance to shear and tensile forces, preventing failure in high-vibration environments like machinery, automotive assemblies, and construction equipment. The headless hex drive design allows for flush mounting in tight spaces, while the cup tip ensures maximum grip by creating a permanent dimple in the shaft, eliminating slippage. With its coarse thread pitch and Class 5g6g thread fit, it offers quick installation and reliable clamping force, making it ideal for precision fastening where alignment and security are paramount. This screw delivers consistent performance, reducing maintenance needs and enhancing operational safety.
