Help Finding Hardware?

I'm going nuts trying to locate a source for a specific size of wire/cable clip/clamp. Here's a picture:
http://users.rcn.com/gwhite/Misc/Wire_Clips.jpg
They are 3/8" wide, and fit a 1/8" diameter cable. The screw hole is ~ 0.150" in diameter, so they easily take a #6 screw. I have a couple in my miscellaneous hardware collection. Some have an oxidized tin finish, and some appear to be bright zinc plated. I have no idea where the ones I have came from, or how ancient they might be. They can't be that exotic, given that I have some from two different sources.
I have tried McMaster Carr, Keystone, Heyco, Digikey, Allied, Mouser, etc., to no avail. Part of the problem is that everyone calls them something slightly different. Most of the clips only go down to half an inch wide, which won't work. The only 3/8" wide clips I can find are from KMC Stampings, and they have a 1/8th inch hole, which won't take a # 6 screw.
I need ~ 100 of these for a product I have in mind, so it's more than I want to drill out, and too few to warrant ordering them custom. The alternative to these clamps is to do a lot more machining, which will probably render the entire effort uneconomical. It took me a couple weeks of pondering to come up with this approach, and given that I already have enough to build some prototypes, I figured I was all set.
I've mostly been focusing on electronics vendors, because that is the most likely source for the ones I have. They could also be used to hold down tubing on something, or control cables on lawn mowers, etc.
Does anyone recognize these & can you recommend a supplier?
Thanks!

Why not just take a couple over to a local electrical supply house and ask for a hundred of "these things"? They will probably tell you where to get them if they don't have any. We used to call them strain relief's.

I can find something similar almost anywhere. Keystone makes most of the ones electronics distributors carry, they just don't make them that small. The trick is finding a source for this specific size & hole diameter. If the places I've already tried don't carry them, the odds of the local electrical supply house having them is pretty tiny. I can give it a shot. I've checked the catalogs of most of the companies that supply such things to the electrical trade, like Thomas & Betts, Raco, etc. & they all have larger and/or plastic clamps.

Looks like you're in luck Doug. $40.00 a hundred is a little pricey but probably not unreasonable in the grand scheme of things.

Do you have room to slide a piece od 1/4" plastic tubing over top of whatever cable or pipe you are using? If so have a look at the M25 midget clips on this page: http://www.brisconelectric.com/STRAPS1.htm
Good luck Lyndell

The clamps holds 1/8" steel rod, and the connection needs to be conductive. In addition, the rod is bent, so it would be a bit difficult to get the tubing on.

That's for 1/8" pipe, which is a lot bigger than 1/8" OD.

Looks like a dead ringer.

Take a look at McMaster 2978T65, it meets your dimensions and does not have a hole (adhesive backed), so you could drill the size hole you want. It's also nylon, but perhaps that is fine for your application.

That one is for 1/4" OD cables. HOWEVER, it looks like they also make a 1/8" one, sized for a #8 screw, which in some ways is even better thna a #6. Allied carries them as well!
THANK YOU! I had checked Allied, but didn't find these. So much for their search engine. As for being pricey, 30 cents each to save a coupel of machining steps sounds like a bargain to me. Also, I bet I can find them cheaper elsewhere.

I recognize them. My father used to work for ma bell as an installer and he had a few pounds of them at home. They were used to secure JKT wire(now apparently called station wire) runs. No idea on suppliers though. Art

Part of the problem is that a lot of folks are now using plastic clamps of one sort or another. For phone wire, I've been using plastic clips that come with nails pre-installed for decades now, and they sell adhesive backed ones as well. I need the clamps to be vaguely conductive for anti-static reasons, so most plastics are out.

How about adding a little contact spring to solve the conductivity issue and let you use the more available nylon straps?

I have some 1/8" one hole clamps similar to what you are asking for. I'll try to grab one and measure it. FWIW, I recently ordered it from McMaster to anchor a wire mesh cage over a small transformer. Someone was worried that some slacker might lay their arm on an exposed 1.5KVA dry transformer and find it was hot. I could lay my hand on it for 30 seconds before being bored.
Oh heck, I kept looking, will McMaster 9434T11 work for you?

Those were the first ones I found, but they are too wide. However, it looks like soemone found something close enough at Allied Electronics, despite my earlier searching there.

See page 18 of this catalog section: http://www.seastrom-mfg.com/seastrom_manufacturing_catalog/Catalog%20Pdf/Clamps%20and%20Brackets.pdf I think that Seastrom p/n: 5300-6-Z3 (zinc plated) might fit the bill.

They look a lot like a brake line clip. I've seen them down to 3/16" normally but I would bet a tap on the curve would make them fit 1/8"
