With the Facom 289.J1 nut splitter set, you can remove seized, rusted, or rounded nuts quickly without damaging the underlying bolt threads. This eliminates the need for angle cutting or open flames in tight or sensitive environments. The set includes two mechanical nut splitters, the 289.M8 and 289.M18, covering thread sizes from M2 to M18 and widths across flats from 2 to 18 mm. By tightening the driving screw with a standard wrench, you cleanly split the fastener with full control. Everything stays protected and neatly organized in the supplied BP.102 plastic case with PL.489 tray.
