First, yes, you should be drilling pilot holes for your screws in your woodworking projects…that’s a bonus tip.
Second, the pilot hole can’t be bigger than the screw and it can’t be too small.
To quickly find the right sizes drill bit, hold the shank of the bit up in front of the screw. You should see only the threads of the screw showing around the drill bit.
