No lead anchors and lags are not the best for hollow masonry, those
are good for solid slabs. For hollow cinder block I would not use any
anchor that expands in its hole. I would rather use a butterfly (or
mushroom style) molly bolt so as not to crack a block with a hole
expanding anchor. Better to have an anchor that expands on the other
side of the hole like a mushroom or butterfly molly. Quarter inch
bolts should be fine for 100lbs on 16-24 inch centers.

I agree with RickH. Toggle bolts would be best for hollow block. 1/4" or
larger should work fine. You just need to drill your holes in the hollow
areas. If it is real cinder block you can drill with a masonry bit and a
good drill. However if you have cement block you will need a hammer drill.

James,

Take a look at toggle bolts when you next enter a hardware store.

I'd plan on it holding 500 - but that's easy.

I like Tapcons-
http://www.concretefasteners.com/anc...tallation.aspx

Get the ones with a hex head. Pick up a 1/2 hammer drill for about
$50 and you'll love these things. Clean the hole out well with the
bit-- use a hex driver to seat them.
[the last few boxes of 25 (50?) that have I bought came with the right
size drill and a hex driver.]

Very good responses from all, thanks !!

Whether I use blue concrete screws or a toggle type molly bolt, do these
products come with a long enough screw so as to go through a 2 x 4 , and
still have enough length to screw into the anchor or molly bolt ?

I used the plastic anchors and all purpose (sheetrock) screws to
fasten 2x2 to non-vertical/non straight block walls. Insulated
between with 1" styro foam sheets and sheetrocked. Did that in 1/2
the basement. Looks great and still ther with no problems 20 years
later.

I also built shelves using nothing but the shelf brackets, plastic
anchors and all purpose screws. Also still there after 15 years.

I don't have anythign heavy stored on those shelves (yet) but the
brackets are the heavy duty ones and I would have no qualms about
loading the shelves heavily.

A lot of people think the load is torque - not so. Most of the load (98%)
from bookshelves and the like, is straight down, not out. If, in the OP's
case, the 2x4 backing sits on the floor, a piddly bit of string will hold a
couple of tons of books in place. (I exaggerate, but not by much).

Tapcon Screws are the best. Use the proper drill bit that is just under
the thread size. Sometimes you have to work the screws in and
out.......Then final tight.....
1/4 " are great.............

really? put a 12" shelf on the wall and put the weight on the front edge.
the load is almost all torque.

Never mind HeyBub. Every so often, he posts messages when he's sober. That
wasn't the case with the message you responded to.

Another option which may be simpler depending on your situation. If
the 2X4s will run floor to ceiling, you can just rest them on the
floor and use brackets and screws at the top to attach them to
whatever wood is available - floor joists or sill plate. (i.e., no
attachment to the block wall at all) I have put up basement shelves
this way and it worked fine. I also have used a powder-charge gun to
attach to the blocks and that worked fine too. -- H

If the 2x4's are orientated vertically and are resting on the floor,
they will support most of the weight. Think of a hundred lb weight
hanging on a 2x4 in free air, just your hand holding it from falling
over. It will not require 100 lbs of effort on your part to stop the
2x4 from falling. the force you are exerting is not vertical, the 2x4
takes care of that. You effort is only opposing the overbalance of
all load being on one side.

HeyBub may have been sober all along.

Of course the OP could add 2x4s to the front of the shelves as well
and have a device that would not require any attachment to his walls
at all.

I've used LN on exterior - painted stucco walls; to adhere faux stone
accents. It's been five years now and it hasn't failed.

The OP could move up a bit and use a butyl caulk/adhesive
(bitch-A-thane). They use it in building rail road cars, buses, and
cars. It might even stick too a ball of lard!!

With a powder charge fastener of the right selection; the studs won't
fail on the block...imo.

I would even consider Liquid Nails and a few fasteners from a Hilti

OK, so suppose your 100 lbs of weight is from a shelf bracket
supporting a shelf 1' wide. Let's take the worst case, that all the
weight is at the front of the shelf. Then that's a moment of 100
ft-lbs.

If the shelf bracket has two fasteners into the 2x4 that are 1' apart,
then the load on the top fastener is 100 lbs of tension. If you are
holding the 2x4 5 ft from the ground and have the bottom end against
your foot, you have to apply a tension force of 20 lbs.

Now if the 2x4 is glued to the face of the masonry wall, and is 8'
long, then a tension force of 25 lbs at 4' from the bottom gives 100
ft-lbs. If the adhesive is along the entire length of the 2x4, then
that's a tension load on the adhesive connection of only 3.125 lbs/ft.

Yours, Wayne

Default Mounting 2 x 4 to block wall ?

Steve, and others:

It looks like Tapcons are ideal, if I have a solid wall. Yes , it is a
cinder block wall. But, I have looked closely in my basement, and I can see
concrete spillover at the top of the wall. So now, I think it has been
poured solid. This cabin was built over 30 years ago, and I have forgotten
some of the details.

I think that my best bet is to "assume" that this block wall was poured
with concrete for reinforcement, and initially try drilling and using the
Tapcon screws. If I see that it is not solid where I drill, then I could go
with some type of toggle/ molly bolt, or the sleeve anchor, right ?

Thanks to Steve and to all others for the very nice comments and advice !!
I have learned a lot from this group.

James
