The GBM features a simple system for stroke adjustment by means of the knurled nut with stroke scale to ensure secure and complete installation of the blind rivet nut. Threaded mandrel locking by means of a lockwasher ensures the mandrels can be changed quickly without the need for tools. The GBM features an ergonomic, non-slip sleeve grip, and the opening spring allows the tool to be handled easily while installing blind rivet nuts. The tool housing of the GBM is made from high-quality, die-cast aluminium, and the tool shanks are forged from chromium-vanadium steel.
