While living in Canada I ordered some Murakoshi joint connectors for woodworking from a distributor in Vancouver BC. This was in the early 1980’s. My supply of these great joint connectors is nearly gone, and I have tried to find a new supplier- either in the US or Canada but without luck. The particular joint connector I looking for is called “Joint Connector Cap Bolt”, “Type JJC-A, 1/4-20” They came in a range 30,35,40,50,60 and 70 mm long. The color was black. Does anyone have a source of these excellent connectors? They were made by the Murakoshi Screw Mfg. Co.Ltd. Japan.

Got a pic. Might be an equivalent under a different name. Is this a furniture connector or a construction connector? You need to provide more info.
E-mail is here.
Website is here.
You may have to use a translator for the web page but I would be willing to bet the person at the e-mail address reads and writes english. I bet they would be happy to tell you who distributes their products in your area.

Just for fun, I used the Google translation tool on that page, first time I've ever tried it. Here is the result:http://translate.google.com/translate?u=http%3A%2F%2Fwww.murakoshiseikou.com%2Fproduct%2Fwood_joint.html&hl=en&ie=UTF8&sl=ja&tl=enforestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)
I recognize the style. That's the guy who wrote the manual for my jointer,

Hi RH.... From Forestgirl's translated post, I seem to remember seeing them, or something very similar, at my local Home Depot. I don't know if you're building cabinets for 'fun' or 'profit.' If you're building for 'fun', visit a cabinetmaker or two in your area and see if they can help you. There are just TOO many different suppliers of hardware, and all of them don't advertise or list everything they carry. If you're doing this as your livelyhood, it may still pay to visit other shops. Sometimes good 'partnerships' come from these visits.
And... there's a big trade show in Atlanta next month. Maybe someone there can help you locate these bolts.

Once the pic was posted on the translated page it looks like something i bought from Lee Valley a few years back. Here's a link to LV page with what i think might be close. http://www.leevalley.com/hardware/page.aspx?c=2&p=45375&cat=3,41306
Doesn't look like they have the full line as shown in the translated web page but they do have some of the line available. (Or what looks to be a close clone)
Hope it helps.

I recently bought some at Lowes's for use on a new router table fence. They have a small selection and I do not remember if they had black. The connectors I bought were dark bronze, almost black. Woodworker's Supply has all the sizes but they are also dark bronze. Woodcraft has a small selection of black connectors.

Would like to thank all those who replied to my inquiry about the Murakoshi wood working jointing systems manufactured in Japan. One person sent me their website (in Japanese and translated by Google), but the illustrations did not show the Type JCC-A, Joint Connection Cap bolt. They may not manufacture this type anymore. For further reference, one person recommended that I attached a jpg of the connector. So, have attached two. One is of the connectors and the second one is the illustration from Murakoshi. These were excellent KD connectors with a 1/2" diameter head by 3/16" deep. They needed to be inserted into the wood and look really aesthetically pleasing being flush with the wood and being black oxidized. If anyone has some of these that they are willing to part with, please reply. Or for some reason I missed that they are still manufactured by Murakoshi and know of a distributor, hey, please let me know. Again, thanks for the replies. rh2008
All the connectors I have seen are not inserted into the wood. The Murakoshi connectors are flush with the wood and really look nice. I will try to find some if they are still make as I would use them.

Look in http://www.mcmaster.com under socket head cap screws. A picture is worth more than a manufacturers name. Chances are someone else makes them.
Thanks RickL, I looked at their web site and although they have something similar, I believe they are for metal machinery. I have written McMaster Carr inquiring about the Murakoshi wood connector. Do not think they manufacturer that particular connector anymore.
The Murakoshi are also a machine screw thread. Just means you thread it on a nut or thread insert of some sort. The socket head cap screws are certainly close enough to be an equivalent. I don't think it's worth asking them about Murakoshi.
try http://www.mcfeelys.com/threaded-inserts They will also have the screws.

When you use the JJC-A connector do you drill a tapered countersink hole or just drill a regular countersink hole?
Murakosit has contact info on their site. You could try sending a FAX or even calling them to find out if they still make the JJC-A connector.

Just a brad point 1/2"diameter drill and about 3/16" deep. I had written Murakosi, but they never replied.
