Concrete screws are designed and manufactured so that the thread of the screws taps into concrete, block or brick. The threads are hardened without making the body of the screws so brittle that the screws shear off.
When you need a fastener that gives you speedy anchoring of your objects to concrete, not worried about the appearance, then an excellent choice is the hex concrete screw.
The DeWALT blue tapper-pro hexagon concrete screw is the only fastener to meet the 2012 IBC and IRC standards for 4 different base materials.
Has a corrosion resistant Perma-Seal coating
Optimised thread design for lower installation torque
Incorporates a gimlet drill point for wood base materials meaning no predrilling is required
