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.
The DeWALT blue tapper-pro philips, countersunk concrete screws are the only fastener to meet the 2012 IBC and IRC standards for 4 different base materials.

Countersunk to sit flush or below the surface of your material
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

Use in various light to medium duty applications in base materials including hollow core concrete slabs, uncracked concrete, lightweight concrete, aerated concrete, chipboard, gypsum block, gypsum board and wood.

Note
Tapper-PRO require the use of specific tolerance Tapper- PRO drill bits for proper installation.
For more information on suitable base materials and installation instructions refer to the Tapper-pro datasheet.
