I ran across and lost a drill gauge, or maybe it was a screw gauge, that had appropriate pilot hole sizes for various screw sizes. I'm pretty sure it was the Irwin brand, but any brand will do. Where can I find this type of gauge that matches pilot hole drill sizes with screw sizes?

Wiley you did nothing wrong but Help Desk Requests forum is really meant to be used to report issues or question with the web site and forums. I am going to move this entire thread over to General Woodworking.

Do your wood screws have a tapered shank or a straight shank over the entire length? The pilot holes in softwood are a little smaller while those in hardwoods are a little larger relative to the overall screw diameter.

I just use the metal drill index box to roughly gauge the drill bit size that I should use.
