Excellent Hanging Shelf Hardware
March 12th, 2011 by KTU | Filed under 6. Interior Materials and Finishes, Notes on Approaches, Park City Mountain Modern.My architects like hanging shelves and I do too. They often take the “cowboy” approach of using galvanized threaded rod and nuts and washers to support the shelving. I wanted something a little more refined, but didn’t want to pay hundreds of dollars for fussy little European hardware bits. Here’s a solution I came up with, which has proven to be excellent in all respects.
Here’s a detail of the hardware:
You need some tubing, some clamp collars, tube connecting nuts, and hanger bolts. I’ll show photos and then provide suppliers at the end.

A 1/4-20 hanger bolt...lag screw on one end and machine screw on the other. Screw this into the ceiling (planning ahead for blocking where you want to hang the rods).

A tube connecting nut, also known as a star nut. You press this down inside your tubing. You need to buy the right size to fit into the tubing. Thread a bolt into it first and you can tap on the bolt with a hammer to insert it. Once the nut is inserted in the tube, you can just screw the tube up onto the hanger bolt until it is tight against the ceiling.
OK, here’s where you get the stuff:
Tubing: I used 304 Stainless Steel, which runs about $9/ft for the polished seamless version or $3/ft for the plain-finish welded-seam version (which looks “satin” and is perfectly nice). You can, of course, use plain steel, which would be really cheap. I used 3/4″ diameter with 0.049″ wall thickness, which is quite standard. You can order it from McMaster-Carr.
Hanger bolts: I used 1/4-20 x 3″ and bought them at Home Depot. (McFeely’s and Rockler also have them.)
Tube Connecting Nuts: I bought these from McMaster as well. They are designed to fit the inside diameter of the tube, which is 0.652″
Double-split Clamp Collar: I bought these from McMaster in stainless. These are pricey…about $10 each. The plain steel ones are about $4 each.
A set up with two 36″ rods and 4 clamps in stainless steel would cost about $70 for the hardware ($100 if you use the polished tubing). In plain steel, it would probably cost about $30.
I used the hanging rods for just the front support. In most cases, my shelves were 1-1/2″ thick (2 sheets of 3/4″ plywood). My finish carpenter routed a 3/4″ dado in the back and side edges of the shelves. He nailed or screwed a 3/4″ wide cleat onto the wall and then installed the shelves over that cleat, holding them in place with a few finish nails.



Hi,
Nice !
I had the same idea for my living room audio/video module, but found the stainless collars a bit pricey… especialy that I needed 20 of them! Instead I’m going with wood pucks that I will drill through and then use an insert and a bolt. I will have to drill through my tubes as well, but they are aluminum (proud Quebecois!) and thicker (120 mil) so it should’nt be a problem.
Can send you pictures if you wish.
Jf.
You might consider using an aluminum shaft collar. McMaster has them for about $3 each, and you can get them cheaper elsewhere I’m sure. Those aluminum tubes will oxidize to a darker gray over time. You can clean them up before installation with a green Scotchbrite pad — when “brushed” with the pad, the surface looks nice and uniform, and the natural finish lasts a bit longer.
