Customer Questions & Answers

When attaching to a block wall is it best to go into the mortar joint or into the actual block? I've heard both.

Asked by: Clayton
I would prefer going into the actual block at a web so you get holding power. If you go into a mortar joint there may be weak spots or even voids.

Can this be used to attach 2x4's to a concrete slab?

I need these to attach some steel plates to the slab, but also need to attach a handful of 2x4's.
Asked by: MrMe
Yes but make sure the screw length will provide adequate depth to hold the wood to the concrete. I would expect that to be about 2" minimum, more if possible.

drill size for 1/4" Tapcon?

what drill size to use for 1/4 inch Tapcon srcews?
Asked by: Dave
The instructions call for a 3/16" diameter drill bit for the pilot hole.

Drill bit included makes the hole to big?

I use the drill bit that is included to drill my pilot holes. It seems to drill a hole too large, because when I put in the screw, it doesn't grip anything and I can pull it out by hand. What am I doing wrong?
Asked by: Bennygirl
Do not use the hammer function on a hammer drill unless you're drilling into solid concrete. For block/brick/mortar joints use the drill only. Make sure the drill bit is set properly in the drill chuck. If the drill bit wobbles when it's spinning re set the bit. Drill straight, and don't "ream" the hole. Also, a little trick: you can always use a plastic anchor to insert into the hole and use these Tapcons. It actually give the screw greater holding strength. Hope that helps

Screws are great and it works over all however the drill bit that comes with this will not allow you to drill many holes at all. I drilled about 10 holes until the bit wore out. I went and got a drill bit from Bosch and used that to finished what I needed to do. So screws are good. Drill bit not so.

Reading all of the reviews took a lot of time and made me hesitate to buy these. Well I just went for it, bought them, installed as per instructions. 1. Hammer drill 2. blow out holes with compressed air 3. impact drill to install them. I installed 100 of these into brick, not mortar, and every single one went in with no challenge, had a super tight grip, none of them snapped. I will continue to use these and recommend to others. I watched a few videos on youtube of people installing them and that was helpful. I'm not sure why so many negative reviews as I had a perfect experience. Best of luck with your project.

Rated 5 out of 5 by from Work great in concrete!!!! These work great in concrete slab that i had to attach some plates to. The included drill bit was COMPLETE GARBAGE! Not straight at all. Had to get my hammer drill and drill bit to bore out straight holes. Tips on using these tapcons 1) Bore hole must be drilled 2) When screwing in tapcon /MUST BE SAME ANGLE AS BORE HOLE

Rated 1 out of 5 by from Test Failure After shearing off smaller diameter Tapcom screws I purchased these screws. Due to the previous failure I found a spare brick that I could try these out on. After drilling the pilot hole of the specified diameter and depth, I tried installing these to determine if they would hold. About 3/4 of the depth embedded the screw began turning freely. I backed it out to find most of the tread material broken off. No holding power for the intended application. Another failure.

Rated 1 out of 5 by from Great in theory.... I have always been intrigued by the Tapcon concrete anchors. Over the years I have tried this product many times only to be disappointed. Even when following the installation instructions exactly, it is hit or miss whether you can actually drive the anchor fully and snug the steel or wood member up to the concrete. The installation time and the lack of consistency just doesn't justify the cost difference compared to a wedge anchor or a lag shield anchor.

Definitely hit or miss as to whether they will bite into the wall or not. They were sturdy for me and I didn't have any trouble with them shearing. They did tend to bend or chip easily though One tip I will give is to definit3ely follow the instructions and make sure all the dust is out of the hole before screwing in. Makes a huge difference!

Rated 5 out of 5 by from Great in brick I'm hanging shutters with these. They are great in brick, but if you are drilling into mortar mix between the brick, virtually all mortar mix will crumble and the screw won't hold. Anything and anybody is trying to drill and get to hold in mortar is a loss cause. Drilling holes in brick is a pain in the butt!
