C joint

Now we're cookin'.

The C joint is an accessory mounting system using a rather simple 3mm bar and c-shaped clip. First used in the Revenge of the Fallen/N.E.S.T. Global Alliance series on a few items in 2009, by the time of 2010's gold-packaging Transformers line and Generations, the C joint has seen much more widespread use.

The system has been given the internal nickname "Miyake joint" by TakaraTomy employees, named after its designer Miyake Tomoya<ref>http://www.tfw2005.com/boards/transformers-news-rumors/359804-united-reveal-shield-jazz-development-secret-story.html</ref>, who first used it on the Revenge of the Fallen Recon Ironhide toy.

Notes

• LEGO has long made use of 3mm bars and clips as well. In practice, LEGO's standard is just the slightest bit larger than Hasbro's, so LEGO clips with even a little wear will only loosely grip C joint bars. Still, LEGO minifigures can cling to your 3mm-bar-equipped Transformers, and their vehicles (assuming they incorporate the appropriate parts) can mount 3mm clip weapons.

• Naturally, this means that similar-construction Kre-O parts should work as well.

• While C joints per se were not developed until the Revenge of the Fallen toyline, many previously made toys have similarly sized bars that can be used to attach C joint weaponry. At least one example dates to the earliest days of the franchise. The Action Master weapons' handles are all C joint-compatible pegs, though the general lack of clips on the robots themselves means this compatibility has somewhat limited practical application for modern figures. Still, you could give the Action Master partners some extra weaponry.
• ...but be careful about it. As with 5mm posts, a bar that appears to be 3mm may not quite be 3mm. TFWiki.net will not be held responsible if you break the clips on your weapons trying to force them onto bars that are too big.
• Because a clip is attached to Terradive's shoulder, he is technically the largest C-joint accessory yet made.
