Customer Questions & Answers

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, you can use these HWH Tapcon concrete anchor screws to attach steel plates to the slab. You can also use the Tapcons to attach 2x4's to a concrete slab, you may want to use a flat head Tapcon if you want the head to be flush with the 2x4's. Please follow the proper instructions when installing Tapcons, which can be found at the bottom of the page at Also, make sure you follow the guidelines for slab thickness, anchor spacing, and edge spacing requirements to ensure the Tapcon anchors have maximum performance. Minimum concrete member thickness should be 4 inches, effective embedment depth should be 1-1/2 inches, minimum edge distance should be 2 inches, and minimum anchor spacing should be 3 inches. All this information should be located on the data sheets that are packaged with every Tapcon anchor pack.

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
Hello Bennygirl, The drill bit for a 1/4" dia. screw is supposed to be 3/16" dia. That allows for the hole to be 1/16" smaller than the screw. It is possible you have the wrong size bit. You must drive that bit in straight, so you don't increase the size of the hole by working it side to side. You can take it back to the store to measure the size of the bit. Thank you for your inquiry. Charlotte of the Home Depot Community.

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.

Installing a rail fence on a concrete deck, ( front porch), and railing for 3 steps. Will this product hold up?
Asked by: Ray
Your question sounds just like my job. I purchased the screws and ran a test to see if they would work. I found a spot where I could do a trial install of the screws. My test failed because my method of installation torqued the screws to failure. The head snapped off using a Ryobi 18v impact gun. You might want to consider a spot to try them out. I returned the unused screws to Home Depot and got a full refund. I finally installed the Railing using "Red Head 1/4 in. Hammer-Set Nail Drive Concrete Anchors" They required pre-drilling the insert holes in the concrete and installing the anchors.

1/4 in. x 2-3/4 in. Polymer Plated Steel Hex-Washer-Head Indoor/Outdoor Concrete Anchors (75-Pack) is rated 2.5 out of 5 by 14.
Rated 5 out of 5 by from 100% success in 2 projects I used these on. Reading all of the reviews took a lot of time and mad... 100% success in 2 projects I used these on. 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 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!

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 Didn't work Tried to use these in mortar to hang a flag pole. Followed the instructions and used the correct drill bit size, etc. They pulled right out. Not even a hint of actually grabbing the mortar.
