A simple invention which allows stops and workpieces to be easily fastened or moved on the bench without levers or other parts getting in the way. The principle relies on a diagonally separated bolt that is connected with a threaded rod and is wedged together in the bore hole by turning the spindle. This allows you to fasten workpieces that are at least 16 mm thick on the workbench with the bolt projecting. Workpieces that are at least 32 mm thick can be fastened without the bolt projecting. The spindle is moved with a toggle, and the stud is fastened to the bench by the winged nut. Borehole-Ø 19 mm, max. worktop thickness 105 mm.
