With the Spit hit M 6X40/12 hammer-in plug, you achieve fast and dependable fixings in brick and aerated concrete. Simply drive the plastic plug and pre-assembled nail screw into a 6 mm drilled hole with a hammer, speeding up repetitive installations such as fixing wooden battening, skirting boards, cable trays, or metal profiles. The flat collar prevents the plug from slipping too deep while providing even clamping pressure against the fixture. Whenever you need to make an adjustment or disassemble your work, the PZ2 drive head allows you to unscrew and remove the nail screw with ease.
