Expansion plug S, without rim, 10 x 50 mm, pack of 50 Supplied = pre-assembled, final assembly by customer. Nominal drill hole diameter = 10 mm. Plug length = 50 mm. Scope of delivery = 50 wall plugs. Min. drill hole depth = 70 mm. Product type = plugs. Rimless anchor sleeve allow the plug to be inserted deeper into the plaster, right down into the load bearing substrate. The anti-twist feature prevents plug rotation in the drill hole. High installation reliability. The fischer S expansion plug is the real deal, and is the classic that has proved its worth millions of times over the last decades. The plastic plug is made of 100% high quality nylon. This makes the plug particularly robust when it is being installed, and guarantees long lasting reliability. As the plug only expands in two directions, the expansion forces can be introduced parallel to the edge of the building material by rotating the plug. This prevents the building material from chipping off when the plugs is installed c
