How to Bolt a Safe to a Concrete Floor & Carpet

Determine where you want your safe located. Remember that the back and sides of the safe are not usually as thick as the front and top of the safe, so a corner may be a good option. Do not put your safe in a public area of your home so everyone will know that you have it. The general idea is that if you have a safe, you probably have something valuable to put in it.

Put your safe where you want it to be. Open the door of the safe and mark the areas where the bolt holes are. Generally, fire proof safes have a single hole in the center of the safe, while burglar proof safes have a hole in each corner. Use a black marker to mark the holes and then move the safe out of the way.

Using a razor knife, cut the carpet away from the areas where the holes are located. It is much easier to go ahead and cut the carpet. If you try to drill through it, the fibers of the carpet may bind up your drill. The hole in the carpet should be about the size of a quarter or fifty-cent piece.

Drill the holes for your safe. Ensure that your drill bit is rated for concrete and is the same diameter as the bolt. If you are not sure, your local hardware store can give you some assistance. Drill the holes about three or four inches deep for a good hold. Using a drill that plugs in the wall will have more power than a battery-powered drill.

Vacuum the dust out of the holes and move the safe back into place. Line the holes in the safe up with the holes in the floor.

Push the bolts down into the holes. If there is any resistance, tap the bolts a few times with a hammer. Tighten the nut that is located on top of the bolt with a pair of pliers. Tightening the nut on the bolt expands the sleeve around the bolt so that it completely fills the hole that you drilled and secures the safe permanently.
