    High-Accuracy Rulers

    With tolerances tight enough for machining detailed parts, these rulers are the most accurate we offer. They're also the most precise, with graduations as small as 1/64", so you can trust them for even the tiniest dimensions. Also known as machinists' rules.
    All are precision made and etched in the U.S. to meet federal standards. Made of tempered steel for extra strength, they keep their shape even after multiple hard hits and drops, so they'll measure accurately for years to come. Their graduations are deeply engraved and blackened with ink, meaning they won't rub off like printed graduations can.
    Satin Chrome-Plated Steel
    Image of Product. Front orientation. Rulers. High-Accuracy Rulers, Chrome-Plated Steel.
    Tough enough to handle most tasks, these rulers are chrome plated to resist rust. Their satin finish reduces glare for easy reading.
    Starrett Rulers—These rulers are manufactured by Starrett, one of the most trusted names for precision measuring tools.
    Calibration Certificate—When precision measurements are required for quality control or by regulation, use a ruler that includes a calibration certificate traceable to NIST. The certificate states that the ruler has passed a test for accuracy, so you can be confident your measurements are correct and consistent.

    Take accurate measurements even when you can't see the exact edge of what you're measuring, such as when working with round corners. Similar to a tape measure, these rulers have a hook on one end to catch the edge of an object, keeping the ruler straight. Turn the stud to remove or reverse the hook.
    Tough enough to handle most tasks, these rulers are chrome plated to resist rust. Their satin finish reduces glare for easy reading.
    Starrett Rulers—These rulers are manufactured by Starrett, one of the most trusted names for precision measuring tools.

    Magnetic High-Accuracy Rulers

    Take machine-shop-accurate measurements while keeping your hands free. These rulers have magnets on both ends to cling to most metallic surfaces. Also known as machinists’ rules, they have the tightest tolerances we offer. They’re also our most precise, with graduations as small as 1/64", so you can trust them for even the tiniest dimensions.
    All are precision made and etched in the U.S. to meet federal standards. Made of tempered steel for extra strength, they keep their shape even after multiple hard hits and drops, so they'll measure accurately for years to come. Their graduations are deeply engraved and blackened with ink, meaning they won't rub off like printed graduations can.
