Composite Floor Fixings
The Ancon ACC is a dowel-type fastener providing a shear resistant connection between timber and a concrete layer.
ACC Composite Connector Range
The Ancon ACC is a blue, galvanised steel, self-tapping screw specially designed for use in the construction of loadbearing timber-concrete composite floors.
The screw is available in two standard lengths. The 205mm length is suitable for use with conventional ceiling timbers and modern slab kits, with a maximum timber floorboard thickness of 50mm (2") between the timber joist and concrete. The 165mm length is ideal for renovations involving traditional 'dippelbaumdecken', common in and around Vienna.
The sharp point and course thread makes the ACC quick and easy to install. No pre-drilling of timber is required.
The shank features an integral ring designed as a depth limiter to prevent over-embedment in the timber. It also acts as a compression bearing in crosswise applications.
