We had the same kind of shelf collapse as seen here, with less drastic consequences.
I went and found some nice 90-degree pins at the store, but noticed a small problem when installing.
The pins on the new supports are slightly longer than the old ones (old pins are 5/16", new are 7/16"). So when installed the nice L-bracket doesn't sit flush with the wall. Is this a problem? I'm guessing it should sit flush so that the wall helps the pin-hole support the weight. Pics at the end.
Should I just drill the pin-holes to be slightly deeper (assuming the walls are deep enough – these holes are on built-in shelves so it's not immediately obvious if they are) If I don't do that, should I file the pins down? Look for similar supports with slightly shorter pins? Or are they fine as is?

The same shape shelf pins are available in the same size you need. The pin is measured at the part that goes into the hole, some are 5MM, some are 1/4" I have never seen 7/16" or 5/16"
