I've used these on solid timber and find them reliable and easy to use provided the correct size hole is drilled. To prevent any breakout I usually countersink the hole slightly which also means the head is flush with the timber.

Found this to be an eay to use insert nut provided the correct size pilot hole is drilled first. There can be a bit of break away around the hole as the nut bites into man-made boards. Correctly inserted it has good holding power.
