Starrett Premium Combination Squares

These are Starrett's top-of-the-line combination squares. Useful for joint layout or machine set-up and as depth, height or marking gauges, they feature long-wearing forged steel heads paired with hardened steel rules with photo-engraved scales. The reversible rules have a satin-chrome finish that reduces glare and resists rust, while the precisely machined heads have a smooth enamel finish. Except for the 4" size, all come with a steel scribing pin and a built-in level vial for determining level or plumb.
