CONFAST3/16" X 2-1/4" Hex Head Concrete Screw Anchor with Drill Bit (100 Per Box)

These screws are fantastic. No plugs to come out at some fateful day in the future. Simply drill a hole and screw them in. And forget. I recently removed some of these screws, from an open air environment, that they'd been in for some twenty years. They came out with the ease that they went in, and virtually free from any rust or corrosion. The screws being in a fit condition for use elsewhere. Being hexagon head, they're very robust against insert tool damage, unlike the Philips equivalents.

Good job

These thinner ones tend to snap under the strain of an impact driver. I suggest purchasing the slighter thicker ones instead. They work excellently. Don't forget to push forwards hard as you drive them in.

Not deep enough to get a screwdriver in to screw them.

We normally purchase these from our local hardware store - and these were perfect! Quick shipping and more reasonable pricing! Also came with the drill bit needed, which worked wonderfully.

I planned on using these screws to drill into concrete. I didn't use the included bit but my own 5/32 SDS bit to predrill the holes. I then used a cordless drill to screw in the fastener. On the first screw the head broke off. I thought maybe it was a bad one so I tried another screw and the same thing happened. I switched to a lower power drill and went at a slow speed and the screws kept breaking. After drilling eight holes and having eight screws break I gave up. I had a few Tapcon screws left so I used them with no problem. Not only are these screws poor quality they are dangerous if you plan on using them for anything that you don't want falling down when the screw snaps.

These are very good quality and the enclosed drill bit work great. Very easy solution and I liked the hex head on the screw better than a traditional slot head. Very nice to have either option in one screw.

High quality product performed very well. Why does it have to be so expensive?

like and not a philips head
