With the Spit pro 6 12X60 universal nylon plug, you achieve a reliable anchor across solid and hollow building materials, such as brick and aerated concrete. The plug expands evenly in six directions to deliver a firm grip. Integrated anti-rotation ribs stop the plastic plug from spinning inside the drill hole when driving in screws, while the shallow collar keeps the anchor from sinking too deep for a neat, flush finish. Simply drill a 12 mm hole to a depth of 75 mm and pair it with screws ranging from 8 mm to 10 mm in diameter to complete your installations.
