Safe Mounting Suggestions

Post by Rider888 » 08 Jan 2019, 7:23 pm

Hi

I am mounting a small safe into a timber floor in my house and was wondering:

1. how long a screw would you recommend? I will be using a M8 and was thinking 40mm to 60mm long???
2. What the of screw would you use? I am familiar with the Ramset Masonary anchors but these are going into a timber floor. Surely I wouldn't be using wood screws? Or would I?

Further info is that this safe is for level 2 storage in SA so into a timber floor is legal.

The other option is that I could mount the safe into the slab but that means the safe would be downstairs and not upstairs where I would like it.

Cheers

I recently mounted one into a timber floor. I had access underneath so I put 90 by 45 timber underneath. Otherwise my fixings would only grab into 19 mm flooring. I used 10 mm by 100 mm long coach bolts a coach bolt really is just a big screw with a hex head on it that can be turned with a socket set Alternatively if your polished timber floor displays putty in the nail holes it is indicative of the structural joists underneath. Fixing into those is going to be very secure

So I can use coach bolts? But they won't be able to go into the floor stud as I cannot be sure that there is a stud in the location I want to put the safe. Is that an issue or will the coach bolts still provide reasonable hold into the timber floor?

I think it’s reasonable to accept that a thief may equip himself with a metre long heavy duty pinch bar. So after you have fastened your safe to the floor if you think that this sort of equipment can destroy your work then it’s probably not done adequately. Nobody wants to come home from work to find their gun safe missing.

One thing I did, although I was using Dynabolts into brick, was to make up some oversized, 90mmx90mmx3mm washers to bolster the 2mm skin of the safe.
I just cut them from some scrap sheet I had left from a trailer build.

Generally, we build timber floors so that you can still access underneath to inspect for damage. Is there no access under your floor?
My safes have 10x100 galv coach bolts with big washers into floor joists and wall studs. Drill holes where required, you don't have to use the holes the safe comes with.

Reverse cowgirl...or cowboy depending on your fancy. ..or your current inclinations.

Find the studds and put 10 thinner coach screws. ..maybe a good option.

The problem usually is not about getting the fasteners to stay in the timber/concrete, the real trick is preventing the head of the fastener from being pulled through the steel wall of the safe. The best way, I think, is a length of flatbar connecting the bolt holes, but big heavy washers are a big help. Just be sure they don't have any sharp edges or points, the first tear in the steel will allow the rest to open like a sardine can.

30 /hex head coarse thread twelve gauge timber screws into hardwood floor is what I would be doing if I could not find the joists underneath.

Hi Rider...just a few questions...

Is it your place--as in you own it, or renting...?

Is the house modern built..?....or do you know when it was built...?

Is the floor carpeted where you want to put the safe...?

And an additional question...do you know what sort of "timber" the floor is...?
For example, if its a modern upper storey, its probably particle board flooring...
The man who knows everything, doesnt really know everything...he's just stopped learning...

Hey Stix, apologies for the late reply but this is still valid for me now in 2024.

House is rented and I want to mount the safe upstairs on the floor in one of the wardrobes.

House built in the 80s. I had a chat with the builder next door and he said that the floor would have joist in them so there is a big, approx 200mm, air gap between the upstairs and downstairs. Yes there is carpet upstairs but I will cut out a safe sized square and mount the safe straight onto the floor then when I remove it, I will put the carpet square back on it.

So my intent is just do that. It's only temporary anyway. Just trying to investigate the most appropriate type of timber screws to use.

Cheers
