    About High-Quality Rulers
    industrial info icon

    What separates a throwaway ruler from one you’ll keep for decades, which type is best for everyday use, and how to compare materials.

    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

    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.

    1/16" Graduations

    Measure the distance your tungsten electrode sticks out from your nozzle for consistent TIG welding. To set the depth of these gauges, loosen the knurled locknut, then turn the threaded gauge rod. Tighten the locknut to lock these gauges into place. Once locked, insert your tungsten electrode into the opening to measure its stick-out. Tungsten electrode stick-out should not exceed the width of your nozzle.
