Great Product..
no studs? this is what you want to use. not the cheapest but the best.

Metric screws, M5-.80×10
I got 2 of the Moem Securemounts to install a chrome grab bar from Delta on a wall between studs. The Moem mounts have a flat aluminum plate that’s threaded to accept the supplied truss head machine screws. However, the mounting flange on the Delta grab bar is fairly thick with countersinks on the mounting holes meant for flathead screws, so the heads of the screws supplied with the Moem mounts protruded from the surface of the flanges. Even without using the supplied split ring washers the covers on the Delta bar stood about 1/8” away from the wall this way. I took one of the screws to Lowe’s and matched it up with a screw gage they had there, and they’re metric, M5-.80. Fortunately they had a pack of M5-.80×10 oval head screws, Hillman brand, that worked much better for my application. Now the covers for my Delta grab bar fit much closer to the wall than before with just a tiny air gap. I hope this is helpful for others who may need different screws than the ones that come with the Moem Securemounts. The mounts work perfectly and were easy to install.

Strong & secure. Hole saw bit needs drywall to engage. Updated remove to reuse info
Strong, smart, but have to be precise if using on both ends of the bar. Only item to be sure to have is a 1 1/4″ hole saw bit. These are inexpensive, fit on any drill and usually come in a pack of assorted sizes.Used these the first time when installing the Moen toilet tissue/grab bar because these mounts came with that item – – easy peasy piece of cake.Later, I purchased the coordinating Moen towel/grab bar to replace an existing normal towel bar. I wanted this new bar to be installed in the exact same spot (in drywall) of the old towel bar so I wouldn’t have a bunch of holes to patch. I purchased these mounts as an add on to give support as I knew I wouldn’t be screwing into a stud.Important to keep in mind is if you want (as I did) to install in the same location as a previous bar, this means you will have the existing (smaller) holes in the drywall where the old bar bracket came off. This creates a problem when using your drill and the 1 1/4″ hole saw. These hole saws are meant to hold themselves centered using a center drill bit, and make the larger hole relative to this center point.Because you already have an existing center point hole, there is nothing for the hole saw bit to hold onto and keep centered. I ended up taking the hole saw bit off the drill, and used a rubber mallet to pound it into the drywall deep enough so the teeth left an impression in the drywall and the hole saw bit would have something to grab onto.I needed the bar to be precisely in the same location because it was centered under a window. If this was not the situation and I could mount it give or take an inch or two, I would have placed the center bit just a 1/2″ left or right of my existing holes. The 1 1/4″ hole would encompass the old screw holes and the hole saw bit would still have “new” drywall” to drill through.A little more work and frustration this second time around, but the clean look and strength of these mounts make it worth it.* * update info on how to remove these mounts- Renovation of this bathroom meant that I was also changing out these grab bars for another style.My brother wanted to re-use these Moens for his bathroom so we commenced on figuring out how to remove them and keep them intact so they could be reused.We could find tons of YouTube videos on how to install, but nothing on how to remove, so here’s that info for anyone who might wish to do so.Unscrew and remove the grab bars. Prying off the cover plates took a bit of delicate work with the edge of a small flat screwdriver. You need an allen wrench to loosen the bar from the mount.Once the grab bars are off, remove the screws that hold the mounting plate from the support insert.What you’ll be left seeing is a thin round plastic ring around the big hole in the drywall.Use your fingernails to pry this ring off the drywall just far out enough so you can get a hold of it with your finger tips. Slide both thumbs into the hole and get a grip on this ring with your index finger.Wriggling and pulling out toward you, pull this plastic ring and arms out toward you.Eventually, the arms will click along the tracks and you’ll be able to get the ring attachment fully extended toward you about 2″ or so.At this point, if you don’t care about reusing these mounts, just use a pair of snippers to cut the plastic arms and the support mount will just fall into your wall.The arms are still attached to the bracing piece so now you’ll need to slide a finger along the top of the hole in order to push the vertical bracing piece to a horizontal position.I used my index finger, but my husbands hands were too large so he had to use a long screwdriver.Once the bracing piece is horizontal, slide your finger straight along the bottom of the hole to keep that piece horizontal and guide it (and the plastic ring/arms) out through the drywall hole.

Awesome anchor for grab bars! The best.
As a home improvement contactor, I’ve been buying these anchors for 20 years plus. Installing tub/shower grab bars is always the customer’s choice of location. You can usually anchor one end of bar to a stud, but the other end is always on question. Rod length, angle, height, etc. These are the best anchors by far that I’ve ever used. Drilling the larger center hole needed for installation also allows some access if you need to put something else in the wall. They are 100% waterproof if installed correctly, no additional sealant required. It’s the best.

As advertised, good in theory but not suitable for my hand grab rail in bathroom. Will keep for future and make sure hand grabs compatible with bracket anchor

Highly recommended.
