I was assembling a cabinet today and screwed the screws into the other panel,the did the same thing on the other side and moved it slightly and every screw blew out of the panels all 8,4 on each side,Looking at where the screw went into the panel it only caught maybe 1/8" on the edge of the panel. the panels are 1/2" thick BB ply. any Idea why this happened.I'm using the kreg jig K3 set at 1/2" and kreg screws says they are for 1/2".
Is this the right way to attach? I did A, but is B a better way?
Drill the pocket hole as shown in "B".
The screw should be directed "INWARD", away from the edge.
When a screw is directed toward the OUTSIDE edge, as in "A", it may blow thru.
Make some tests with the drill bit boring a 1/16" shallower.
I use the "micro jig" when joining 1/2" material.
It's a good practice to make sample test pieces, before proceeding to the final work-piece.
This method helps to insure you're getting acceptable results.
