King Arthur's Tools 13750 5/8"-11 Universal Nut for Angle Grinders

• Hexagonal head with flat base which secures pressure evenly over the blades
• Fits all 5/8"-11 threaded shafts & standard size on most Manuf. disc grinders

UNIVERSAL NUT is re-engineered with a recessed back. Now you can securely tighten ALL King Arthur's Tools to your angle grinder with this truly "Universal Fit" nut. The recessed back allows discs to be easily tightened on different size angle grinders. The Universal Nut allows 2 blades to be tandem mounted on 4-1/2" (115 MM) or 5" (125 MM) angle grinders. NOTE: Only blades with 5/8" (16mm) and 14mm center hole sizes may be tandem mounted. The Universal Nut easily tightens all KAT accessories. Can also be used when fitting any other 5/8" arbor accessories on disc grinders, simply use a 13/16" spanner, socket, spark plug socket or adjustable wrench, it is much easier and safer than the traditional two pin spanner wrench.
