​One of the most common questions about safe bolting down gun safes involves types of floors. So first I’ll look at how to bolt your safe to a wood floor and then to concrete. Neither floor is especially difficult, and you’ll be finished in no time flat!

​Generic Safe Bolting Instructions

To ensure safety and theft prevention, gun owners like to attach their gun safes to the floor. Regardless of whether or not you are working with concrete or wooden flooring.

There are a few common tips to use when bolting a safe to the floor:

  • To get started, you’ll need a couple of simple tools like a marker and measuring tape, and maybe a stud finder.
  • Bolting a safe to the floor won’t do you any good if you don’t position it properly.
  • On wooden floors, you may be able to attach the safe to floor beams if they are large enough or close enough together.
  • A tape measure and stud finder will help you locate these beams.
  • Mark an outline of your safe on the floor where you plan to install it.
  • Using your marker, mark holes on the floor from inside the safe where drilled holes are.
  • After you do that, and you verify what you are going to be drilling into, you’ll be ready to start drilling!

​Mounting to the Floor

​To do this, you’ll need special tools, like a drill strong enough for the job, and maybe an impact hammer depending on the fasteners you are using. You’ll also need a special concrete drill bit, so you can actually drill the drilled holes.

Some manufacturers will sell complete floor bolting kits. If you can get one that works for your safe, then you are halfway there. Otherwise, you’ll need to check with your safe manufacturer for recommended size, and acquire the right hardware and drill bits to use in mounting the safe.

Most floors can be drilled into with a regular drill and concrete drill bit. Some may require an impact hammer if the drilled holes to be drilled are large enough, so you’ll want to make sure what you need ahead of time.

Once you’ve chosen the tool needed, and have identified where to drill, you can start drilling. Make sure ​you also have the best safe for the​ house so you won’t encounter any more problems later on.

The most common way of bolting down a safe to the floor, concrete, or wood floor is to use expanding anchor bolts. These anchor bolts expand tightly in the hole, making for a very tight, snug fit. You only need common hand tools to install expanding anchor bolts, making this a very easy job.

​Mounting to a Wooden Floor

​When you want to secure your gun safe (or really any safe) to a wooden floor, there are a couple different approaches, just like when opting to hand-carry a gun.

If you have a crawlspace, you’ll might consider just drilling through the floor and using large nuts and washers. Or you might be able to fasten a safe to floor joists with lag screws.

If you are going to try and mount to floor joists, you’ll need to find them and determine their spacing with a stud finder. Next, you’ll have to see if the hole spacing in your safe allows you to mount to at least two joists. You may need to bolt your safe to a wider sheet of steel first, and then the steel to your joists.

The tools are fairly straightforward, with the hardest part being locating the mounting points and simply drilling the holes. Most any decent hammer drill options with do the job, and the proper bits are cheap and easy to get. You’ll need basic hand tools to attach the anchor bolts to ​ensure the safety of all your guns and ammo, ​but that’s about it.

​Attaching to Walls

​Are you trying to figure out how to anchor a gun safe to a wall? This isn’t as tricky as it sounds. In fact, it is much like floor mounting, inasmuch as you mostly have to figure out where you’ll be mounting the safe, and identifying the anchor points, similar to the look of a​ good rifle and gun storage cabinet on the market.

As before, identify the studs in the wall where you will be attaching screws. It is not advisable to mount directly to drywall, as the safe could be torn away from the wall with little effort.

You should also avoid any rooms or walls with moisture such as the air conditioner or the bathroom as it can impact the gun safe itself. Instead, you must mount to wall studs, making sure not to hit any electrical wiring or plumbing. Make sure to keep a gun safe dehumidifier on hand to prevent any damage moisture can bring.

Once you’ve figured out where to hammer drill, then you can fasten down your safe with the appropriate screws or lag bolts. You may want to fasten your safe to both the floor and wall for maximum security. Of course you can do one or the other, but why not both if you can?

Installing Upstairs

Are you trying to figure install a safe upstairs? Well, you aren’t alone. Getting a safe upstairs can be a problem in and of itself, and then you have to concern yourself with making sure your floor can support the weight, and then bolting it down.

Fortunately, this is also a simple matter. Most floors can handle the weight of many common heavy safes. With a heavy enough safe, you might consider just fastening it to a piece of wide sheet metal that can’t fit through doors and call it good.

Assuming your floors are structurally sound, you can also follow the same instructions for securing a safe to a floor. Or you could attach it to a wall. You should consult with a skilled safe installer or building contractor before proceeding though, just to make sure everything will work out for you.

A lightweight safe will be easier to move and install, but also easier to steal. A safe with a fingerprint scanner is good for protection, but not all safes have it.

So you probably want to go ahead with a heavy safe, and fasten it down with any of the several proven methods I’ve examined. Or you could gamble on crooks not coming prepared to haul off a monster safe, but why chance it?

​How to Install a Floor Safe to the Floor

​Floor safes are very useful gun safes because they can be so easily hidden. However, installing them requires a bit more work, and maybe best left to a professional. You will have to cut and dig out a concrete floor, or modify an existing wooden floor.

How to Bolt Your Safe to Concrete Floor

Learning how to bolt your safe to concrete floor may be the easiest option in terms of the type of flooring. After you’ve determined the size of the hole you need to cement in your safe, simply cut and dig your hole, then place and cement your safe. New construction is even easier, as the safe can be installed with the floor.

Bolting to Wooden Floor

In a wooden floor, you’ll have to cut a space for the safe. Then build a wooden framework to support the safe and whatever you use to permanently secure it, like cement. That way, it won’t easily be moved and will be safe for the children. You could also use an commercial grade epoxy to literally glue your safe into place.


​When you are ready to begin bolting, the work itself isn’t hard. It mostly requires careful use of common hand and power tools and attention to safety and detail. Often you can get the same people who sold you your safe to install it for you.

Once you’ve selected and bolted down your safe, then you can rest secure, knowing that you’ve taken extensive steps to protect your firearms and other valuables from unauthorized access and theft. The hardest part may be in selecting the safe itself!

Either way, as you can now see, securing your safe is not a daunting task, and should only take a little bit of your time in most cases. Good luck!
