What size screw do these holds take? We are planning to install them into a concrete retaining wall, so we will use mortar/brick screws...

We were placing into plywood but used standard deck screws. Out of all the holds there was only one hole that was drilled a little funky and made it tight to get the screw in.

We are using deck screws but the threw holes are 1/4" and the head is around 1/2" you could use 1/4 20 bolts.

I believe we used a #10 or #12 three inch wood screw into 3/4 plywood.You could use 1/4" masonry screws with them. And need to factor about 1/2" to 3/4" extra length for the thickness of the holds.

my guess is that they will not work with mortar or bricks, but I haven't tried using them for that purpose. They are so much better at the usual task than others of the same size though.

My husband said for concrete, you should drill a hole first and use an insert that the screw actually screws into. We hung ours on the wall and we also had to search for a sturdy screw with a small enough head to fit. I must say it was worth the trouble, we have gotten a lot of compliments on our wall art. Good luck.

I'm not at all familiar with actualy sizes of screws. If you are familiar with security hardware, these are the standard size. To be honest, I'm not sure if they make another size. I think the brackets are around an 1" or maybe and 2" long max? They are meant for wooden frames.

Hi Larry, to be absolutely honest we hung them unto concrete walls and we had to use special pugs and screws for that. Unfortunately I'm not into those details as I hired a contractor this. What I can say however that I was very happy to see the quality of the product. My kids really enjoy them one is pre teen and the other much younger. There is a lot of info about installation on the net. I'm so sorry that I could not have been of greater assistance. But its not hard to get the info.

Probably too late to help you in particular, but...Just use plastic wall anchors and then screws to fasten to regular wall. Metal anchors if masonry wall. Increases the load the screws can hold

Use loctite, OR there's this kewl new invention called the internet where you can find just about anything including replacement pivot screws in whatever size you need. ;)

You mean inside a concrete column? Yes if it is wide enough. Or do you mean mount on the concrete column. Yes if it is wide enough but you will have to drill using concrete drill bit holes for mounting screws. I bought special screws for my brick mount in mortar. I do not remember if they were 1/4 inch or 3/16 inch by 2 1/4 inches or so. I think you better ask some man to help you drill and mount. The screws they provide are more suitable for wooden attachment.

Drill in to the Brick and Not the Mortar joint and you should be fine. Make sure all 4 bolts engadge the holding sleeve that they screw into, sometimes 3 out of 4 will engadge and you have to pull that one out and spread the sleeve a little more to make it wider so that it grips onto brick in wall. Important - Do not drill holes too big use drill bit size indicated. Better to be tight and hit anchor into wall with a hammer.

i would suggest get appropriate size concrete anchor screw if you want to mount on concrete floors. take the bottom plate off and take it to hard ware store to match it with the largest size anchor bolts you can get.

They should slide with a little elbow strength. Tight squeeze. I never used screws if I remember. Good luck

I would purchase different wall anchors if you need to anchor to driwall. I believe I was able to place at least a pair of the screws that came with these in a wall stud and I used much heavier duty anchors, purchased separately, for the others.

Any regular drill can hold these bits. I wouldn't put them into any really high torque drill and obviously not into a hammer drill though.

Yes, using concrete screws anchors. You will need to drill into the wall using the appropriate drill and then put a contrete anchor into the hole to accept the screw. Not that complicated.

to be honest I cannot recall the length of those screws in particular, however if they are too long you can always find a shorter screw at a hardware store that would better fit your frame. I used these in a commercial application and they work great, we were even able to salvage most when deciding to move the art around and reuse the hardware.

These screws are supplied with the bracket kit. They are machine screws, if you do not have these you will have to contact the mounting bracket manufacturer or the original place of purchase. They definitely come with any mounting kit, as I have installed quit a few. Otherwise you can try various size machine screws, either English or metric threads, no more than 3/4" in length. You do not want them to bottom out before they are tight on the bracket due to being too long.
