Red Head 1/2 in. x 3-3/4 in. Wedge Anchor 10CT

I bought these to replace some horrible hardware that was included with some base plates I purchased recently. Installation is pretty straightforward, drill a 1/2 inch hole in the concrete (deep enough to seat the anchor with the nut flush with the top of the bolt). Smack the anchor into the hole. Tighten the nut until tight. If the bolt pulls up to high, it can be cut down with an angle grinder and a cutoff disc.

Very easy to use. Seems to grip and hold very well.

Perfect for my installation

Works as described and recommend to anyone who needs one

I used these to secure a heavy bag stand. I had to tighten them down after a few days of use, but after that the stand seems to be solid.

need to hold down - these do the task. just drill drop tighten.

Make sure you have the proper size drill bit and the slab is thick enough.

I bought stops for my shop but the concrete lags weren't doing the job.. bought these now nothing moves well worth it.
