Proper block wall anchors for tv mount

[mark32]

I will be mounting a tv on a hollow block wall in the near future. I've had good performance from Tapcons in the past, so that was the first one to come to mind, especially since they now make them in larger sizes like 5/16" and 3/8". I also thought of sleeve anchors, but I've never used them before, lead shields/anchors also came to mind but that's another item I have never used. A friend recommended toggle bolts, which I really like for drywall but never used them for concrete blocks before. Anyone have a favorite for such applications?

Back in the day I'd hang 10 lb ABC extinguishers in block wall with 1/4" toggles. Actual weight was about 16 lbs. Never had a call back or complaint.

I took a quick look at a PDF from Powers, and they give the allowable tension load for a 1/4" toggle in hollow block wall as 70 lb and in shear, 120 lb.

I like toggle bolts also.

For any hollow spaces toggles are great but I happen to like these better.

I find them stronger and easier to work with.

I don't like plastic for anything with an expected service life of "forever". It never stops cross-linking and will eventually suffer brittle failure.

The plastic has absolutely nothing to do with supporting the load.

It is a handle to install the metal part, then you tighten it up like a zip tie, fold the extra plastic over, it breaks flush with the wall and now you can thread a bolt into it the metal part.

Cool. Never saw them before.:thumbsup:

I saw a cabinet guy using them and picked some up.


The metal part is one piece instead of the two pieces that fold on toggle bolts.

You can really tighten these up much more than a toggle, I have a habit of breaking toggles when tightening them up. :rant:

That Yankee temper.

but seriously, I gotta try those.

I blame the bottom of the barrel hardware electrical supply houses carry.

I still carry both on the truck, toggles are still handy for some things.

Looks cool. I'll check it out next time at Lowes.

Ahhh, I misunderstood.

I have used them a few times.
The frustration of the "use once" nature of standard toggle bolts persuaded me to try them.
I like the greater strength for same hole size too.
But they are a problem for the occasional thing that must mount perfectly flush to the wall. (Other anchor types except old toggle have similar problems.)

I'm with Iwire, I tried one of those snap toggles for the first time about a year ago and they worked great!! I did like them much better than regular toggles.

If it is inconvenient to get to Lowes (140 miles for me!), the "never drop wall anchors" are also available at McMaster-Carr.

I never have liked toggle bolts. I would probably look at a anchor like this and using that type of setting tool.

that's what i usually use, however, those plastic guided toggles
are a knock off of the ones Hilti sells... and they work very well.
i have about six of them holding up a 2" angle iron triangular
support in my backyard, a foot off the ground. the framework
has strut welded on it, and supports my pool heater, filter, and
all the valving. been there about ten years now....

Lead anchors went out of style in this area.

I have heard it became a violation for us to use them for ceiling work so we just do not stock them.

Yes, I don't think you are permitted to use them for overhead work, but with block you are never sure what part of the block you will be drilling into, and you can use the lead anchors no matter where you drill...that is not the case with toggles.

Thanks Bob and co. for the input. I too was told by a cabinet guy about those toggles and their usefullness. But like Don just posted, you'll have to hit the block's cavity in order to use them. I always wanted to try those caulk-in anchors, hmm, I'll just bring both anchor types with me, maybe the larger Tapcons too. For this application I have the most confidence in those toggles though. Bob, I sent you a PM.
