Clickbond Studs
In composite planes (our Cozy IV, for example) I have used probably 100 of the ClickBond studs. Everywhere I want an Adel clamp in the structure is a ClickBond. The aileron and rudder hinges are held on with ClickBonds (that is something like 40 right there). The autopilot servos are held in with ClickBonds. The landing brake is held on with ClickBonds. On and on, you get the idea. I've used lots of them.
Here are some keys:
I don't use their adhesive. I find it finicky, tough to tell if you've done it right, and they sometimes fail. I use a Dremel tool with a cut-off wheel to cut 6 slots around the edges of the bonding disc. This helps keep it from rotating. Then the surface I am bonding to is roughed up in a ~2" circle. I flox the ClickBond in place, then do a 2 BID layup over the clickbond. Popping a hole in the BID works fine, and use a straw or heat shrink tube to keep the epoxy off the threads. Peel ply over the BID and let it cure.
For critical applications (rudders, ailerons, landing brake, etc) it is exactly the same, but the ClickBond is inserted from the opposite side of the layup, through a hole. Then same flox, BID, peel ply.
Installed as I have outlined I have not had one disbond. If you want to test it put one in as described then pull it out with a pair of pliers. You'll find that the layup is destroyed long before the ClickBond comes out.
