1/4 inch x 2-1/4 inch - 40 Pieces Wedge Anchor Zinc Plated Heavy Duty Fastener for Concrete

I ended up mushrooming two of my four anchors hammering it in a concrete hole. The hole was drilled with the proper depth and width but the force still ended up altering the hammering point at the top. Ended up having to use a file to remove the material so I can place on the screw. Using a punch helped a little.

Works fine no issues

Had to order twice. The first time the package opened in the mail and was sent back without me every seeing it. I ordered again and it took a week longer than estimated to get the order. The product was perfect.

Drill a hole to the correct depth, insert the hardware, whack it with a hammer, and it's not coming back out. To be honest I spent a lot of time overthinking which of these anchors to buy, so here's a message to all the other over-thinkers out there: This kind works just fine. Probably the others do too, but this one DEFINITELY does. Get this one and move on to over-thinking something else.

Used these to anchor 6 x 6 posts to concrete

Great for safe mounting

Used on my new 9k 2post lift and it I have to retorque them down after every few cars are on the hoist I have 8 in of reinforced concrete that was just poured 2 months ago not quite sure if it's the nuts backing off and loosening or if they're pulling out of the concrete recommendation says on here 110 foot pounds I've even tried to torque them to 115 and 120 and they still seem to back off after the hoist is used a few times not even putting anything heavy on the hoist just cars and SUVs not even sure if I would trust button a half ton truck up on it with these anchor bolts

I got to install a tire changing machine worked perfect.
