Universal Nut As An Accessory, Especially For ALL Round Holey Galahads. We highly recommend using our specially designed Universal Nut #13750 (standard angle grinder) or #14000 (metric grinder), especially for any round Holey Galahad to secure the accessory. Here’s why!
Every round profile Holey Galahad has a different inner wall design and slightly thinner metal thickness than flat Holey Galahads. The engineering and manufacturing design incorporating the 6 holes conflicted with the compatibility in using most manufacturers grinder locknuts to tighten the round disc. The disc was generally seated below the arbor, which did not allow over-width grinder lock nuts to secure the round Holey Galahads, causing the discs to spin freely. Our recessed Universal Nut overcomes this problem. Using this specially designed nut, you simply seat any style Holey Galahad, but especially the round profile, over the arbor and tighten. The depression in the universal nut seats over the arbor and securely tightens the disc. It also seats snugly in the deep well center of any Holey Galahad.
The flat Holey Galahad body is slightly thicker than the round model and, in most cases, when seated over the arbor, will be level with, or rise slightly over the arbor. In this case using the angle grinder manufacturer’s locknut will tighten and secure Holey Galahad.
If using both round and flat Holey Galahads, get the respective size Universal Nut that suits your grinder. It will make securing all your accessories a breeze.
