Painted Wrenches

Last Updated: 10/01/2017
This article discusses an efficiency improvement recently implemented at our shop.

At a glance, I can tell the difference between a 10mm wrench and a 6mm or 14mm wrench, as in: sizes that are at least 4mm apart ... but sometimes I've mistaken a 10mm for a 11mm, or 12mm or on a bad day, even a 13mm wrench. To tell the difference, when it's that subtle ... I have a hard time with that, so that means I end up squinting at some very small numbers, trying to read them, to figure the size. Over the years, I've wasted a lot of time doing that, albeit just a few seconds per incident, but it adds up.

So, I've color-coded them, as in:
- Orange is 6, 10, 14, 18, 22, 26, 30
- Green is 7, 11, 15, 19. 23, 27, 31
- Yellow is 4, 8, 12, 16, 20, 24, 28, 32
- Purple is 5, 9, 13, 17, 21, 25, 29

... plus in black sharpie, the size number is written on there too, in as large a number as space reasonably permits. Better.
