Concrete anchors and concrete screws both can be used to fasten items to concrete. Concrete anchors, generally speaking, expand in a pre-drilled hole, while concrete screws tap or cut threads in a pre-drilled hole.
Drop-in Concrete Anchors
Drop-in concrete anchors consist of two pieces: a male threaded bolt and a female threaded sleeve with a knurled end and slits. The slits allow the lower part of the anchor to expand. The sleeve is dropped in and then set solidly in place with a metal set tool. After the sleeve is in place, it cannot be removed from the concrete, though the male bolt can be removed from the sleeve.
Wedge Concrete Anchors
A wedge anchor is a male threaded bolt with a shielded wedge on the lower part that expands as a nut is turned against a washer on the bolt. The bolt and the shielded wedge are one piece, not two separate pieces as with the drop-in and sleeve anchors. Wedge concrete anchors are easy to insert, yet they hold very firmly in concrete. Once in place, wedge anchors cannot be removed, but the nut can be removed from the anchor.
Sleeve Concrete Anchors
A sleeve anchor consists of four pieces: a threaded bolt and a metal sleeve tube with large slots and narrow crosscuts, plus a nut and washer. The slots and crosscuts allow the sleeve to expand when it is tightened by the bolt. Furthermore, a smooth wedge at the bottom of the threaded bolt pulls upwards to force the bottom of the sleeve to expand.
Carefully study the concrete anchor's product specifications before installation. Be aware of the concrete anchor's weight limitations, both in terms of shear and pull-out strength. Do not over-torque concrete anchors. Use safety glasses when striking or turning concrete anchors.

Then continue the anchor into the pre-drilled hole in the concrete.Pound the top of the anchor with the hammer.Place the washer and nut on the end of the exposed bolt and turn the nut clockwise. Firmly turn until it can no longer rotate.
