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

These work very well in concrete and stucco. They are a great value. If you were to buy they at the big box stores, you would pay three times the price. I use these for all kinds of projects. My latest use was to mount a retractable hose reel to my house. You do need masonry drill bits to drill the holes to put these into. Also, it would be nice to have a hammer drill to speed up the process.

Worked as a concrete anchor should. Good quality as in fit and finish and size. Will purchase again.

I purchased the Stainless Steel and installed two behind a water spigot whose hole was drilled too large by the person who installed it. A little PC concrete plus these anchors seem as hard as the brick I attached them to. I bought a couple of stainless steel screws locally and now my water spigot is held firmly to the brick, but I can still remove it within seconds if needed in the future. Great product!To install these easily, you needed a drop-in anchor setting tool. I didn't realize this until after I received them, so I had to delay my project a few days while I ordered and waited for the tool to be delivered. I highly recommend you guys sell a package of these with the tool, too! It would only cost a few more dollars and allow a new customer to get everything they need at once.

Worked very well in in both concrete and stucco. Do make sure you use a 5/16" drill bit instead of the 3/8" recommended.Also, don't drill too deep or you will have a harder time "setting" the anchor in place using their tool.

Good quality as I used this to install an outside gate (it's a cheap plastic gate so I wanted to keep the option of changing it out in the future so this allows me to unscrew the bolt without drilling more holes later). You'll need to buy a drop-in anchor tool to get it to work properly; it will likely break or not work if you use a nail and screw to hammer it. This does not have a "lip" to catch the edge of your hole, so you will need to be careful how deep you drill your hole through masonry (some of the more costly versions has a lip).

The 1/4” anchors take a 5/16” hole for installation. I drilled a 3/8” hole per item description. I wasted my time … and have a wrong size, unusable hole … reviews said 5/16 but I don’t read all the reviews every time. I feel I should have been able rely on the vendor’s description.I threw them away and reordered from another source.

They work like they are supposed to
