Being a repair nut, the b&m-TRIMNUT® is designed to make dirty and damaged threads usable again. The functional principle comes into effect when screwing on and off. By using local forming, the repair nut eliminates not only impact points. It also removes coating residues and weld spatter as well as rust and heavy dirt.
At the same time, the b&m-TRIMNUT® is also capable of forming a thread in conjunction with a corresponding bolt geometry. In these cases, the nut acts as a tool and fastener in one.
