The AKUMA® Nut Buster is a heavy-duty manual tool designed to split and remove seized, rusted, or rounded nuts without damaging the underlying bolt or threaded shaft. It uses a hardened steel cutting blade driven by a screw mechanism that applies focused pressure to crack the nut cleanly in half. With its adjustable jaw, it accommodates nut sizes from M6 to M24, making it ideal for a wide range of automotive and industrial applications.

Constructed from impact-resistant steel, the Nut Buster resists flexing and distortion under high loads. It’s a safer, faster alternative to grinding or torching stuck hardware—especially in confined spaces or around flammable components. The compact design makes it easy to carry in a service vehicle or toolbox, and its replaceable cutting head extends service life. This is the go-to solution when fasteners fight back.
