Compare calculators
Both calculators run independently β change the inputs on either side to compare results.
Wood Moisture Content Calculator
Determine the moisture content of lumber from wet and dry weights, then estimate how much water must be removed to reach a target moisture level for woodworking or construction.
Wood Screw Pilot Hole Calculator
Determines the correct pilot hole diameter for wood screws based on screw size, wood hardness, head type, and thread pattern. Use it to prevent splitting and ensure full thread engagement in any wood species.
Pilot Hole Diameter
0.14 inches
About 1/8"-5/32" is typical for #8-#10 screws; the 0.14" example sits here. Drilling deeper than the screw length prevents the tip binding in hardwood.
Pilot diameter scales with screw gauge; woodworking guides recommend pilots roughly 70-90% of the screw's root diameter, from about 5/64" for a #6 to 11/64" for a #14.
