With the Spit pro 6 universal nylon plug, you achieve dependable fixings across solid and hollow building materials, including brick and aerated concrete. Its 6 expandable zones and anti-rotation fins activate instantly as you drive the screw, keeping the anchor firmly locked without spinning in the drill hole. The shallow lip ensures a neat, flush finish on the wall while preventing over-insertion. Designed for a 6 mm drill hole diameter and 40 mm depth, this plastic plug pairs with 4 mm to 5 mm screws to mount skirting boards, cable ducts, and lightweight wall fixtures securely.
