ITWBrands 24325 1/4" x 2.25", Steel, Hex Washer Head Concrete Anchors, Silver

Does the job as intended.

Michael Baldwin Product worked great. However, the package had been opened and resealed crudely with tape and the masonry drill bit removed. .Project is complete after a trip to Ace for a bit.

Bolts are great. The included drill bit is junk. Worthless after drilling two holes in brick. Bought a set of 2 at the local hardware store for $5 and they lasted the entire job.

Good quality for the price.

This does what you want pretty simple and straight forward

I have been using Tapcons for 30 years and never had an issue. The screws themselves are rock solid-reliable. They seat well in drive bits, run in quickly, and bite reliably. Ask them to do something outside of their design parameters, and they will cam-out or snap at the head, but typically, worry-free. Quick note to novice/new users- order screws a tad longer than you think you need and drill holes a bit deeper. The screw tip is a long, shallow-taper by design so you essentially lose the first ~1/4" of thread bite.Two reasons for my rating "ding": 1. The included bit- good for a couple of holes before it gives up, but unless you have magically soft concrete, free of aggregate, you certainly won't pop a hundred holes. The bit in this package was missing (see ding 2), but I have used many other ITW/Tapcon bits for reference). 2. The packaging/shipping- the screws and bit, I suppose, were supposed to remain in their thin, polystyrene, flip-lid box. However, that un-robust box was placed in a flimsy padded envelope for shipping. Needless to say, I got a mostly mutilated envelope full of loose screws, poking out everywhere, no bit, and a crushed manufacturer's box. I don't think all 100 screws were there, but no time to count or return- needed them NOW. You will not be disappointed in the product, but good luck with the packaging.

Such a great product!

5/6 of the ones I have tried to install have sheered off at or just below the surface of the concrete.
