UNIVERSAL NUT: We specifically made two Universal Nuts to mount our tandem combinations, one for each of the standard 5/8” (5/8-11) and metric M14 14mm threaded center shaft sizes found on angle grinders worldwide. Only the KAT Universal Nut makes tandem combinations possible. With its 21mm hex head, it also replaces the different manufacturers’ size 2 pin spanner nuts.
UNIVERSAL WRENCH: For adjustment of a safe, simple and secure fit, use our made-to-fit Universal Wrench, or your wrench, socket set or pliers. The Universal Nut and Wrench secure most disc accessories to any manufacturer’s power tools that have either a 5/8” or 14mm spindle thread shaft. This includes electric and pneumatic angle grinders, sander/polishers and sander/grinders ranging from 4-1/2” to 9” (115mm to 230mm).
UNIVERSAL FLANGE: Misplaced your bottom disc flange located at the bottom of your grinder’s center shaft?
And then frustrated by the difficulty in finding the manufacturer’s replacement part… We’ve heard this frustrating tale many times over! So we designed a simple solution, the Universal Flange.
