Review: Gregg - Worked perfectly
Review: good and seem like name brand, exactly right length for dimensional lumber attachment - They seem like the name brand or good enough clones I can't tell the difference. These 3-1/4" ones are exactly what you want to attach 2" dimensional lumber (actually about 1-1/2" thick) to concrete and have the screw heads pull down flush into the wood rather than sticking up. Strangely enough the local hardware stores all sell 2-3/4" as the longest you can get with these normal heads (called "bugle head") and any longer they switch to a big flat head that stays against the outside of the wood and remains proud. 2-3/4" ones can work if the wood is perfectly flat against the concrete and you don't overdrill or wobble out the hole at all. Any slight deviation and you'll find a frustrating failure rate with 2-3/4" tapcons going through 2" dimensional lumber. These are MUCH better and have enough extra length to cross a small gap and pull the board tight as anything. I've put in almost the whole box with every single one holding strong. I didn't use the included drill bit and didn't even check if there was an included torx bit. Both of which are better if you buy separately. I found great success with generic concrete drill bits here on desertcart. The ones that are included with tapcons are trash and will frustrate you.

### ⭐⭐⭐⭐ Works as expected

Generally works as expected but I did twist one off attaching a pocket door frame to our basement floor.
