A Cutting Machine Screw is a type of screw with a deeper thread and a cutting groove design, usually used to fasten and connect harder materials or in high-load environments. Unlike ordinary self-tapping screws, Cutting Machine Screws usually require pre-drilling before installation.

Cutting Machine Screws are typically made of stainless steel or carbon steel and come in different sizes and pitches to suit different uses and needs. Their cutting groove design can more effectively cut and remove metal or other materials, and provide better stability and fixing force during installation. In addition, Cutting Machine Screws can also undergo surface treatments such as zinc plating or heat treatment to improve their durability and corrosion resistance.
