Screw Sizes

For screws measured in inches, diameters of 1/4 inch and smaller (for machine and sheet metal screws) or 5/16 inch and smaller (for wood screws) are expressed with a # and a whole number (ex., a screw with a major diameter of 3/16 inch is a #10 screw). Smaller numbers indicate smaller diameters.

What can I use instead of a 5/16 drill bit?

5/16 converts to 10/32. Assuming your bit set is that granular, the next larger size is 11/32, and the next smallest size is 9/32. Those aren’t necessarily common sizes, however. The next size up in x/16 would be 6/16, which is 3/8.

Which size drill bit should I use?

The diameter of the hole you drill should be slightly smaller than the diameter of the screw. So, for example, if you’re using a 3.5 mm screw, use a drill bit with a diameter of 3 mm. If you’re using wall anchors as well as screws, the drill bit and anchors should have the same diameter.
