Frustrated, unable to memorize nut and bolt sizes? I found this tool and purchased both Metric and SAE. This is going to help me finally put some order to my excess nuts and bolts!  |

Wait till you get some bolts with JIS threads just to add a bit of confusion to the pot.

Ya'll are killin' me! LOL
I had to look that one up!
"The thread form is now redundant and has been replaced by Unified and Metric threads but there are many applications in which it is still used. ... British Standard Brass (for which there is no British Standard) is based upon the Whitworth thread form with all diameters having 26 threads per inch (tpi)."

To add insult to injury, whitworth requires different wrenches...

If you find an odd bolt in your office chair and it looks like its M6 but with a 1.25 pitch its a 1/4" whitworth thread, its widely used in the far east in furniture manufacture, and if anybody has a set of M5 x .9 pitch left hand thread taps they dont want I might be interested just snapped my last no2 tap and use them to make JIS brake rods for late 60s Suzukis.
The 1/4" whitworth thread is also used in camera and camcorder tripod mounts so any doubt get your camera out.
