Concrete screws have alternating high and low threads. The lead thread on the masonry screw does all the cutting of the masonry material while the screw is being installed. The lead thread will dull and hit a point where it will no longer be able to cut threads and will stop screw penetration.

Can you put screws in cinder blocks?

Concrete screws are sturdy, plastic-coated screws with chisel-type edges that cut threads into cinder block and other masonry materials. A hole 1/4 inch deeper than the concrete screw’s depth should be drilled first with a cordless drill or hammer drill.

How do you attach heavy things to cinder block walls?

Things You’ll Need The anchor used to hang heavy objects on a cinder block wall must grip the sides of the anchor’s pilot hole tightly.
