Wensilon(100 pcs) 1/4"-20 Premium Zinc Plated Carbon Steel Drop in Anchors Assortment, Knurled Drop-in-Anchor for Solid Concrete, Internal Forced Expansion Screw Bolts

Used these anchors to mount a manual tire changer to my garage shop floor. They worked great..

Look just like the much more expensive drop in anchors.

Good quality insert. Be aware that you don't have to buy or use the setting tool if you have the right size punch. The idea is simply to drive the internal wedge down to expand the bottom of the insert. Remember to use caution when drilling your holes. If the hole is even slightly oversized the insert won't expand enough to grip the sides of the hole. Also, keep the hole plumb or your stud will be at an angle.

These might be good in concrete floors, but not cinder block applications. It requires a tool to drive the insert wedge to expand the flange that should bite into the concrete. But driving it into cinder blocks pushes it in too far and fails. Once installed flush, there is only a 1/2" thread available for installing a fastener, which is not enough in most cases. I trashed them since I could not get them to anchor properly.

Do not drill the hole the size they recommend, way to big in block or concrete. You also need to purchase the hammer in tool to make these work.

Bought these to mount a tire changer and a table to concrete pad that i poured. Went in flawlessly and seem to hold great. They do seem cheaper than some of the others that i have seen but time will tell how well they hold up

Excellent anchors for brick pavers.

I suggest going smaller with the hole than they recommend. I drilled my holes to the recommend size and these would just drop in. I would set them and they would pull out without too much force. If I had it to do over again I would drill a smaller hole where I would have to hammer them in(not beat real hard). I ended up pulling mine out, installing new ones, and then using epoxy in the holes. Hold strong now.
