    It easily tightens and removes King Arthur’s Tools Universal Nut. The recessed hexagonal head design in the wrench makes securing and releasing the 21mm hexagonal head Universal Nut easy.

    Problem:  Power tools from different manufacturers all have proprietary different sized nuts, disc flanges and two pin spanner wrenches, none of which are compatible with each other. 

    Solution:  This frustrating issue is now resolved with the Universal Wrench, Flange and Nut Set however, if you only want to replace your angle grinder’s manufacturer’s nut, then use the KAT Universal Nut which is best used with our 21mm hex head wrench.

    Secure & Tighten any Accessory: Using our Universal Nut and Wrench , easily attach flap disc sanders, grinding wheels, chainsaw blades (single or in tandem) carbide discs, wire brushes, masonry blades, polishing and buffing wheels as per manufacturers’ instructions. The Universal Nut fits all 5/8” or 14mm spindle thread shafts, including Ryobi, DeWalt, Porter Cable, Milwaukee, Black & Decker, Hitach, Makita, Bosch, Fein and other makes of electric and pneumatic power tools, from angle grinders, sander polishers and sander/grinders.
