Machine Screw Diameters
The Miniature Locomotive, July-August 1954
Machine screws are numbered as distinct from Cap Screws, Bolts, etc, and range usually from #0 to #12. A convenient method of finding the exact diameter if a table is not handy is as follows:
- Multiply the number of 13 and add sixty thousandths. The answer will be thousandths.
Examples:
- #0 -- 0 multiplied by 13 equals 0, plus 0.060 equals 0.060
- #3 -- 3 multiplied by 13 equals 39, plus 0.060 equals 0.099
- #5 -- 5 multiplied by 13 equals 65, plus 0.060 equals 0.125
- #10 -- 10 multiplied by 13 equals 0.130, plus 0.060 equals 0.190
