M12 x 1.75 Self-tapping steel insert with Three Bores is designed for creating robust, high-strength, wear-resistant, and vibration-resistant screw connections in materials with low shear strength. These materials include aluminum and aluminum alloys, brass, bronze, cast iron, duro, and thermoplastics.
These threaded inserts feature a tapered bottom and three cutting bores, allowing them to cut their own threads when inserted into a receiver hole. This ensures a completely secure and stable anchoring in the host material.
The threaded inserts with cutting bores are specifically engineered for materials that are challenging to machine. The thicker wall design enables them to withstand greater cutting forces, which are evenly distributed across the three cutting bores.
