This video shows why multipurpose Atlas Bolts and concrete screws are firm favourites with installers.
Quick and easy installation are just a couple of the reasons that these Hex Bolts are so popular, but the main benefit for installers is that these multi-purpose, self-tapping bolts and screws, are ideal for fixing into a wide range of materials including concrete, brick, natural stone, marble and slate as well as wood.
