1/2" x 2 inch Drop-in Anchor, zinc-Plated Carbon Steel Expansion Sleeve Screw Bolts kit for Concrete Drywall (50 pcs)

These expansion sleeve anchors are of good quality steel construction, with a zinc coating to resist corrosion. The product description indicates they are designed for use in solid concrete or stone. I think by examining them that they will be great anchors in those materials. The quality is good. Fifty cents each is reasonable. I procured the 3/8" variety which conveniently requires a 1/2" hole. Half inch masonry drill bits are very common and cheap. My first job with these will be to floor mount a manual tire changer. These changer stands must be anchored because horsing a new tire on to a rim, it fights you back pretty hard. I was looking for a floor mount solution and these will be perfect. Stationary power tools as well, a great, easy floor mounting solution. Just drill a 1/2 inch hole in the concrete floor. Blow out the dust with a compressor. Drop an anchor in and bolt the unit down. When I'm done mounting the tire I plan to just pull out the anchors and slip in pieces of 1/2 inch dowel or rebar as filler in the holes. That way the anchors don't get dirty and rusty. I'm sure more uses will come down the pike for these sleeves, securing bolts to concrete or stone. Preppers take note.

horrible packaging, but after I got over that I tried these, and they sure have holding power be sure to drill the right size hole, or they will not have max. holding power the kit is a great value vs. what you pay for the big name brands... but pls, package these better so they are not all over the box they are shipped in....

Out of all the variety of concrete anchors, not many allow you to remove a bolt from an anchor and then re-install it at a later time, at least without having something sticking up from the floor. Those of us that aren't blessed with unlimited space for tools we only use once in awhile will find a good solution in these sleeves. Like another reviewer, I wanted to mount a tire changer and be able to detach it from the floor when it was not being used. At some point I'd like to get a pipe bender and it will be the same situation. These work great and the cost is actually pretty low compared to almost any concrete anchor at the big box store. Based on other reviews, I'm guessing that the vendor has upgraded the packaging at some point, because the sleeves I received came in a small box that is only as tall as the sleeves - literally there is no empty space in the carton, and the little inserts have no way to come out with the sleeves standing up inside it. I'm happy with these and glad I was able to find these on Amazon after striking out locally..

3/5 inch outside diameter??? Really? Who's bright idea was that? That converts to 0.6" or 15.24mm. There are NO drill bits in those sizes. You will need a 19/32" drill bit for these. Yes, they make them but you will have to look hard for one. I really dislike having to buy an uncommon and dedicated drill bit to accommodate these but if I have to ......... One reviewer said he used a 9/16 drill bit and it worked after he over tightened it a little but that hole is actually starting out at 0.025" too big. I don't think the knurling on the ends is deep enough either to get a good grip on the concrete either. I can't say if these work yet because I have to order a 19/32 (8.5/16 inch) inch drill bit first. I would try the 9/16" but I don't want to end up with a loose anchor or have to patch the hole if it doesn't work properly. As things stand right now, I cannot recommend these. Should the 19/32" bit work perfectly I will revisit this review and update my progress.

I'm going to write this review based solely on my initial impressions. They seem of decent to very good quality, only time will tell if they can hold up against the elements, so I can't speak to their long-term quality. you will need to purchase a set tool for best installation results, but I'm sure you can get around not having one.

Plastic inserts to keep plunger in all fell out in shipping and I had to re insert the plugs in almost every anchor. They work great afterwards as intended

The box these anchors were packed in was weak and broke open even in a padded shipping envelop. The anchors are much shorter than any I have used before. The knurling is shallow and I wonder if they will even grip during installation. There is no information provided with the anchors but by trial and error I determined that a 1/2" hole is required and it has to be pretty darn precise for these to work. I recommend trying to install one where it doesn't show and doesn't matter before actual installation.

This is a review of the Horiznext 5/16" x 1-1/6 inch Drop-in Anchor. Box of 100 drop-in anchors. Drill a hole in concrete, push one of these anchors in and screw in the 5/16 inch bolt (not included). As you screw in the bolt, the anchor expands and grips the side of the hole. If the hole is slightly too large then you will need to prevent the anchor from rotating so the bolt can go deep enough to expand the anchor. The title mentions these can be used with drywall. I don't see how that is possible because the anchor will simply rotate in the hole. Drywall is not solid/strong enough to hold the anchor in place. The ad says to drill a 2/5 inch hole. I have never seen a 2/5 inch drill. I measured the anchors with a micrometer and a 10mm drill will do the job If I am bolting a bracket to a concrete wall I will first drill the hole, insert the anchor, screw in the bolt until the anchor expands. Then I will back the bolt out of the anchor, place the bracket over the anchor and re-screw the bolt into the already seated anchor.
