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. |

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. Dave M. |

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.] Jim |

James 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............. jloomis "James" no wrote in message ...

James 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. LdB |

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. |

You effort is only opposing the overbalance of all load being on one side. 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 |

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 |
