Great product for wall mounting support for those times a stud isn't in the right place. To confirm this will work, test-install the 14/-20 bolt into the threaded toggle before installation. You don't want a malformed/bunged thread to prevent this from working once it's in the wall. And thread the bolt by hand to make sure the threads are properly engaged, followed by a drill-driver.

These are great. We hang small speakers using these. Much more reliable than spring toggles (which sometimes don't work well but it's hard to tell)

i wanted to love these things. the idea of easy/fast install and strong was appealing. i used a full box of 50 installing various things (closet systems, garage organizers etc) in a new house, so gave them a solid college try. they're in my walls holding stuff up, so that's worth something! but were kind of a fiddly PITA. here's why :

- with a machine screw type fastener, precise alignment between the screw and threads is critical. otherwise, the bolt cross threads when attempting to fasten. which is exactly what happens with these snaptoggles. the same flexible (kind of genius) mechanism that allows you to fold the toggle, insert it, and unfold it on the other side, does little to precisely align the toggle once zipped down. if the threads are off parallel ever so slightly, it's a no go. and yes, I was using the right bolts. they threaded effortlessly in my hands. ~50-60% of the time, insalled, they went in smooth as butter straight away. but the other 40-50% of the time, when alignment wasn't spot on, any time gained on the fast ones was lost trying to get the bolt not to cross thread on the toggle head - screw in, nope, screw out, jiggle a little, screw in, nope, screw out, jiggle a little more, again and again and again. a fiddly PITA. I was able to get all but one to eventually take but at a loss in terms of time. super annoying too when trying to crank through projects.

- due to the cross threading issue, even when zipped down as tightly to the wall as possible, the toggle would occasionally spin in the wall preventing the bolt from catching.

- the plastic portions of the fastener seem especially brittle. any little bit of twist force and the heads are prone to snapping. again, problematic given the cross thread issue. so a few times the toggle simply snapped off and fell into the wall when trying to get a bolt started. which makes me question their strength. I did NOT independently test their marketed holding values given the redundancy i had in studs.

- lastly, the 1/4" bolt was just slightly bigger than the standard in just about everything I had to hang. of course. because i refused to throw the entire box out, i had to drill out many a closet / garage hanger bar in order to accommodate the 1/4" bolt diameter.

comparatively, wingits do a much better job addressing the alignment issue. never had a cross threading issue. but are much slower to install and require a bigger insertion hole. why i reserve their use for very specific circumstances. likewise, the good 'ol molly doesn't have the same threading issue as the alignment is fixed to the head. in the end, molly's were much easier/faster to install albeit at loss in terms of (marketed) holding strength. but not enough to have made a difference in my (and many) cases. my instinct for overkill in this case cost me.

Best drywall anchor for heavy objects i've ever used. If you have screwy drywall thickness, this is the thing to use. I used it to mount shelving brackets.

These are the best anchors out there. Extremely easy to install and have way more load capacity then any other anchor. Obviously they don't come with the bolts/hardware because they fit ANY WALL from 3/8" to 3-1/2". Would you expect them to provide every bolt size for every possible wall thickness in that range for every anchor that comes in this kit? Of course not.
