With the Spit hit M 6X30/5 hammer-in plug, you achieve fast through-fixings in solid and hollow substrates such as concrete, brick, and aerated concrete. Thanks to the M-slot design, the plastic plug expands only after being fully inserted into the 6 mm drill hole. The flat collar prevents the plug from slipping too deep while ensuring neat clamping for fixtures up to 5 mm thick, such as skirting boards, profiles, or cable trays. Simply drive in the pre-assembled screw nail with a hammer for instant hold and easily remove it using a PZ2 bit.
