Description

These rules interchange with those supplied in Starrett combination squares and sets. Made of hardened steel with photo-engraved markings, they are offered with either a regular finish or a no-glare satin-chrome finish that resists corrosion.

Imperial rules are graduated in the 4R style (with increments in 8ths, 16ths, 32nds and 64ths) and metric rules are graduated in millimetres and half-millimetres on both faces. Imperial/metric rules are graduated in 64ths and millimetres on one side, and 32nds and half-millimetres on the other.

The rules for the 6"/150mm square heads are 0.080" thick by 3/4"/19mm wide; those for the 12"/300mm heads are 0.090" thick by 1"/25mm wide. Rules are straight and parallel within 0.001" per foot.

Made in USA.
