Sizing considerations for wood screws:
Taken from the Shopsmith woodworking tip of the day.
Sizing considerations for wood screws:
PILOT HOLE DEPTH
In Hardwoods - equal to length of screw
thread
In Softwoods - equal to 1/2 of screw
thread length
BODY HOLE DEPTH
Equal to length of screw shank
MAX. COUNTERSINK DIAMETER
Equal to outside diameter of screw head
MAX. OVERALL SCREW LENGTH
Approx. 1/8" less than combined
thickness of workpieces being joined
RULE-OF-THUMB FOR SCREW STRENGTH
A longer screw of smaller diameter is
stronger than a shorter screw of larger
diameter

Good on ya and thanks. Great help for a bush carpenter like me! I shall save this and print it in letters large, and attach to a suitable surface in my shed where I can refer it before I start screwing (and don't edit this 'cause I'm dead serious!.
Regards.
