More decades ago than I’d like to admit to I bought a set of rules – 150, 300, 600 MM – from Bridge City Tool Works. They had English on one side in 32nd & 64th and metric in 1 & 1/2 mm on the other. Since I work in metric but often need to translate to designs & tools scaled in english, I loved them. My 300 mm rule has gone AWOL and after two weeks of searching my pretty well organized shop I am loosing hope of finding it. Only Starrett still seems to make anything like this, but their website is laid out in hieroglypys that I can not decipher. Styles are described as 3R, 4R etc. and I can’t find any decoder ring on their website. Can someone point me toward an explanation that will help me find exactly what I am looking for.

4R metric 0.1 mm

Might try a site “”

In the current Starrett Precision Tools catalog #33 (online or download as PDF) those classifications are defined on pp. 290-91

Thank you. Couldn’t they have found a way to hide that info any better? Probably not. Nice products but truly awful web site. 64ths is overkill for my eyes; 32nds is my limit. I could buy both a metric and imperial rule from woodpeckers for $15 less but they seem only to come in 16th. I suppose one can split the lines and be pretty close to 32nds.

The graduation you are looking for is 36.

Have your say...
