Red Head Poly-Set #12 x 1-7/16-in Sleeve Anchors 20 -Pack

Simple to use.

I used these to anchor down my flagpole bracket/holder into a rock wall and so far, so good.

Get the correct size drill bit & anchor

Used to mount step to concrete, worked great.

Works Well, Would purchase again.

Works Well but the drill size that they say you need to drill is a bit to small. Also Make sure you insert the screw at least 3/4 of the way in before using a hammer to drive it into the hole. I used these to secure the bottom plate for some closet doors and it worked very well. I also recommend you use a hammer drill to drill the holes as a standard drill will take you forever to get the holes drilled.

Best Drop-In Anchors

I've used these in multiple locations. They are strong and when drilled and inserted properly hold a lot of weight.

Inexpensive and easy to use

These worked great to anchor the mailbox.
