Our MX Direct Fix Masonry and Concrete Screws feature a self tapping high/low thread to give excellent pull-out resistance in masonry, concrete, brick, stone, block and even wood materials.
Rapid and effective direct through fixing that replaces traditional fixings, such as nylon frame fixings, hammer screws and lightweight expansion anchors.
6mm diameter pilot hole for brick, block, masonry and wood. 6.5mm diameter pilot hole for harder materials, such as hard concrete and stone.
Zinc plated and yellow passivated for increased corrosion resistance.
Non-flammable steel fixing conforms to BS 7671:2018 – for supporting wiring systems using materials which are unlikely to collapse prematurely in the event of a fire.
Self tapping concrete screws are used for fixing of window and door frames, timber beams, battens, wooden laths, facades, metal profiles, panels etc. into a variety of materials.
