But with just a small handful of theright toolsand materials, it’s possible to do soefficiently and safely.
What Are Concrete Anchors?

Concrete Screws
Concrete anchors and concrete screws both can be used to fasten items to concrete.
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.
Wedge concrete anchors are easy to insert, yet they hold very firmly in concrete.
The slots and crosscuts allow the sleeve to expand when it is tightened by the bolt.
Safety Considerations
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.
How to Use Drop-in Concrete Anchors
Drill the Hole
Drill the hole.
Clear out the hole with the shop vacuum.
Place the Sleeve in the Hole
Drop the female threaded sleeve into the hole, slit-end first.
Place the Set Tool
Place the narrow end of the set tool into the sleeve.
Warning
Do not pound on the bolt itself as this may strip the threads.
Use only the set tool.
Add the Bolt
Add the threaded bolt and washer to the sleeve.
With a wrench, turn the bolt clockwise until it is firmly set in place.
Place the Wedge Anchor
Fit the wedge end of the wedge anchor into the pre-drilled hole.
This expands the wedge, holding the anchor in place in the hole.
Then continue the anchor into the pre-drilled hole in the concrete.
Pound the top of the anchor with the hammer.
Firmly turn until it can no longer rotate.
Turning expands the bottom of the anchor.
