Some reviews mention a few pop out here and there. Anyone use adhesive or glue as you hammer in?

I've never had one pop out, I did try and remove one with negative results! They are rated at 1,200 lbs. pullout. Adhesive may, or may not help.

First, drill a hole deep enough through the board/concrete, then hammer it in. A hammer alone will not drive it into concrete or brick.

This is an old question, so you probably already have an answer.... The mortar may work better. Bricks are hollow and can blow out or crumble with the drilling and hammering.

can you use this anchor to attach stair posts to concrete steps?

Asked by John September 4, 2018

Answers

You will need a 90-degree "adapter" piece of metal. Fasten one side of the metal to the post, and then anchor the post with these. You will need to hammer drill a 1/4" wide by 3" deep hole in the concrete to receive the anchor. I used these to anchor a post for an overhang.

Answer

I typically use these to anchor treated 2x4 or steel C channel plates to basement floors. I would agree that they would not leave a protrusion that would be bad for tires and would consider a like use.

I used this product in a Oregon hyperbaric chamber office. I needed a product that would hold inch and a half pipe 20 ft lights at a time on a cement tilt wall. This product secured face plates everything 8 feet, horizontal and vertical. Not a problem and plenty strong. Easy as drinking a 1/4 inch hole. Insert pin and hit with a hammer. That causes the product to spread in the wall and secure heavy items. I have even used them on ceiling installation projects. Meets all weight items and look neat for inspector.

I use these to mount wood storage racks to a concrete block wall. The columns are slightly over an inch thick and there are spacers (to allow the shelves to slide up and down a little) which comes to about and inch and a half. These go the same amount into the block as are very strong. One nice thing is that after you do the first hole, you can drill right through the uprights to get the other two mounts in perfect alignment.

Replacing a rusted metal wall footing with 2 x 4 lumber. These work really well in a 45 year old basement. Drill holes and pound them in -- that 2x4 isn't going anywhere. I used a deep-well socket to tap the shoulder of the anchor into the 2x4, then a couple whacks on the nail head to lock it in place.
