We found that these worked excellently and almost never came loose during competition. The only drawback is that they're pretty expensive at ~$20 a piece.

$$$ Yikes!!!

If you need more pins take a look at 98320A135.

They should be a direct replacement for a lot less. $1.39 / piece. I've used them on 3 robots over the last 2 seasons without issue.
