Concrete Screws

Often used for fixing into concrete, brick and blockwork, stone and timber, or most commonly for the installation of window and door frames, multi-fix concrete screws are 7.5mm diameter screws available in lengths from 40mm up to 200mm.

Designed to replace older masonry fixings, the drill size required to use these screws is 6mm.

Using Concrete Screws

Drilling a slightly deeper hole than required is often advised when using concrete screws. This is done to allow for any dust and debris to gather at the end.

The countersunk torx drive uses a T30 insert bit. Our full box quantities include this but it can be ordered separately if required.
