CONFAST 1/4" x 3-1/4" Wedge Anchor Zinc Plated (Box of 100)

Needed anchors for my shop construction. These worked perfectly and better than half the price at local hardware store. Highly recommend.

The 3/8" by 3" long anchors were easy to install, and they appeared to anchor well.I installed 16 additional anchors to better hold down 8 carport structure support-posts.I drilled the holes in the concrete with a 10mm (I did not have a 3/8" drill) carbide tipped drill bit, using a rotating hammer-drill (cuts concrete "like butter"), and used a squeeze-bulb to clean out the holes.I put a washer and nut on the anchor to avoid inserting the anchor too far, and hammered in the anchor. The outer end of the anchor seemed to be well designed to tolerate the considerable necessary hammering without substantial deforming.Finally, I tightened the nut with a ratchet-wrench, until I could tighten it no more.Note: Make sure that you drill deep enough before inserting the anchor, because you are unlikely to be able to remove the anchor. Yes, on my first anchor hole, I was concerned about drilling too deep. Apparently "too deep" is not a problem with these anchors, at least with a proper tight-fit in the hole.One flange was too close to the edge of the concrete piling, so I drilled one hole substantially off vertical into the piling and that appeared to get the expansion end of the anchor far enough from the side of the piling to tighten the anchor without cracking the concrete. The second hole, I drilled more noticably off vertical, which was probably even better.Overall, it was a success experience with a type of anchor that I had never used before, but would cheerfully use again. Instructions would have helped, but probably most users are not first-time users, like I was.

Very nice product.

Good value, also

Anchor bolts were as expected and a good price.

Set 24 of 25 and not one failed. Set in green concrete (at 7 Day break) then came back at 28 days and tightened to spec. Seller shipped fast and kept my project on schedule.

I purchased these anchors for use in a poured concrete pier. The anchors are well made. The box of 25 included the nuts and washers in separate plastic bags. The packing box was even sturdier than needed. The overall zinc finish was bright and shiny. There was no uneven coverage on any anchor. The threading was sharp and defined. A very "jewelry" like finish. I have faith that when I install these fasteners they will hold fast. The "proof is in the pudding" and until I actually drill my holes, in cured concrete, and torque to the specified loading, I can't speak to the hold down power. These are to be used to anchor post metal "stand-offs, and they will be subject more to lateral loads than being pulled out of the concrete. Of course in tornado conditions, the decks "lift" will come into play. If my project experiences high uplift forces causing pull out of the anchors I will update my review after we pick up after the tornado. Such a failure will be more likely from my poor application of the product than any fault of these anchors. (After initial torqueing, the wedged anchors will have the voids in the drilled hole filled with epoxy to prevent wiggle from those lateral forces I expect from expansion and contraction.)Grumpy 46

I use these as anchors with which to move granite boulders. I've had good luck with 3/8, 1/2 inch moving boulders up to 3T. Mostly dragging but in some cases moving up an incline. Tend to be a bit weak in shear, so insure that you tighten any lifting eye or bracket firmly. Torque specs are 30 ft lb for the 3/8 and 60 ft lb for 1/2 inch; I can't see how you could overtighten them.Do not allow persons or body parts to remain under the load when lifting hazardous items.

Quantity and quality both are good

Really nice anchor bolts!

Perfect items - did the job!

worked well, no issues

Estos tornillos los usamos para colocar anclajes en rutas de escalada en la roca, buen aguante y fáciles de colocar.
