Quarter turn/Quick Disconnect Fasteners

[jbennett]

Does anyone know where I can find some high-strength quick disconnect/quarter turn captive fasteners? I've looked into CAMLOC/RAM fasteners and have not found anything that will work. The standard Camloc series are not strong enough (looking for something with allowables similar to an NAS1993 or other 10/32 screw) for the application, and the heavy duty series tend to be too large of a diameter to function in this application (must be .250 dia or less). The fasteners must be approved for aerospace applications, and something maintenance friendly and easy to find (for replacement parts) is preffered. I've nearly exhausted all of my resources so any information/help is appreciated.

We ended up sticking with the Livelock fasteners I had originally spec'd out. There was nothing in the "quick disconnect" fasteners that would hold up for what we required. For info on the livelock fasteners, go to Alcoa's website, and look through their structural panel fastener PDFs. For exact numbers you'll have to contact them, but they're very helpful in that respect.
