Crowne Tools Nip Nut (2-Pack) — The Plastic Nut That Keeps Steel Off Your Tile A grinder's steel flange nut is a tile-scratcher waiting to happen. One accidental touch on a porcelain miter and you've got a burn mark or a chipped edge on an expensive piece. The Nip Nut replaces that steel nut with impact-resistant Acetal plastic — non-marking, so contact with the tile no longer means damage. Its cone-shaped, low-profile design deflects contact away from tile edges and buys clearance in the tight corners, inside reveals, and shower niches where grinder hardware always seems to be in the way. It threads onto standard 5/8"-11 grinders, and it's especially handy on flangeless blades like the Butter and Caviar, where the nut is what actually holds the blade. Why Tile Pros Choose It Non-marking: Acetal plastic won't burn or scratch tile Saves edges: Cone profile deflects contact and reduces chipping Better clearance: Low profile reaches tight corners and reveals Universal fit: Standard 5/8"-11 thread Finish-friendly: Porcelain, ceramic, stone, and polished tile Two per pack: A spare for when the first one rolls off the bench The cheapest insurance your porcelain will ever have: Pennies against a cracked tile Pro tip: Run it any time you're grinding close to a finished face — miters, outlet cutouts, niche returns. On flangeless blades it doubles as your mounting nut, so keep the spare in your pouch.
