I am not sure if this is the right sub-forum to post this but here it goes!
Hello fellow Houserepairtalk members!
I am trying to figure out how to securely install nice modern looking shelves on my living room wall. These shelves will be 100% made by myself from pine wood, unless I find good quality pre-made shelves. These shelves will be hund without apparent brackets, so I need a way to secure them with anchors or something like that.
I am not sure if such anchors already exist, but I couldn't find any looking in the hardware stores around my house.. This is why I am thinking about my own design. See attached picture.
Basically, a hole sufficiently large enough to pass a 3/8" hollow wall hanchor butterfly (whatever they call it) is drilled through the sheetrock and the furring strip behind it.
A shallow (1/16" perhaps) 7/8" OD counterbore is cut on the previously drilled hole. This counterbore will be used to sink the 7/8" washer.
A 3/8" nut is screwed onto the 3/8" hollow wall anchor's threaded rod until the anchor is secured onto the wall by pinching the sheetrock and furring stip firmly together. A smaller washer can be used between the nut and the large washer if the large washer's center hole is bigger than the nut.
At this point, there will be a (somewhat) strong steel rod coming out of the wall.
The 5/8" OD x 3/8" ID smooth threaded insert is firmly crewed onto the 3/8" hollow wall anchor.
The shelf is inserted onto the smooth inserts.
Ive done this before for all kind if things, mirrors, heavy frames, even TV's but normally, the protruding length of the anchor is not much (under 1/2"). I am fairly comfident this would work but as you can see, it involves a fair bit of work and a certain level of craftmanship, otherwise, the studs will not be 100% level and the shelf will not slide onto them easily (at all). Another potential issue is the perpendicularity of the anchors in respect to the wall. If they are not exactly 90 degrees to the wall, the shelf will not fit or wont be straight on the wall.
If someone has better ways to do this, I am hearing!! Other than that, there must be a proven efficient way to do this... Im not sure how Ikea's shelves of that type are hung on the walls....
These shelves will only support up to 20 pounds (decorative items, small picture frames, etc....) so no superior strength is required.
So I am waiting for comments/recommendations!
