With the Spit pro 6 universal nylon plug, you achieve a secure and reliable hold in virtually any base material. Whether you are fixing into solid concrete, brick, or hollow walls, its 6 expansion zones expand uniformly or knot tightly behind the cavity. This eliminates guesswork during renovation and installation jobs. The immediate expansion prevents the plug from spinning while driving the screw, while the shallow rim keeps it from slipping too deep into the drill hole. Simply drill an 8 mm hole with a minimum depth of 50 mm and pair with 4.5 mm to 6 mm screws for a clean, flush finish on every project.
