Answer to Question #270015 in Civil and Environmental Engineering for Angel Nodado

Question

True or False: A precise way to get the right drill bit size in predrilling is to match the shank size with the drill bit size.

Answer 1

Just pick up the wood screw, hold it up to the light so You can see the threads and the shank,

Then You pick up drill bits until You find one You can place in front of the screw and see all of the threads but just covers most of the shank. If the wood is soft maybe the shank of the screw is just a teensy bit larger than the pilot drill. Having the drills in a nice index box makes it easy.

so the answer is TRUE
