These hardened stainless steel rules have an anti-glare pearl chrome finish. This contrasts with the clear bold markings to form a rule that is far easier to read than many others we have come across in the past. These quality rules have millimetre graduations on the upper edge and half millimetres on the lower. The reverse of the rule has conversion tables from imperial to metric as well as handy information on thread tapping sizes. The rules read zero from one end with a hanging hole at the other.
