Frequently Asked Questions
Common questions about Drill Bit Sizes for Screws, formulas, and expected usage.
Why are pilot bit sizes different for hardwood and softwood?
Hardwood fibers are denser and split more easily, so hardwood pilot holes are typically larger for the same screw size.
What is a clearance bit size used for?
A clearance hole lets the screw shank pass through the first board so threads pull the second board tight against it.
Should I match bit size exactly every time?
Use these as starting points, then adjust slightly for wood species, screw type, and desired holding strength.
Do I still need countersinking?
For many woodworking joints, yes. Countersinking or counterboring helps seat screw heads cleanly and reduce splitting near edges.
