Starrett Certified High-Accuracy Rulers


Ensure reliable, repeatable measurements with these rulers. They include a calibration certificate traceable to NIST stating they have passed a test for accuracy. All meet Fed. Spec. GGG-R-791H, which establishes uniform standards for ruler accuracy, graduations, and size. They're also known as machinists' rules. They have a corrosion-resistant satin-chrome finish that reduces glare and wear-resistant etched markings. These rulers are labeled with numeric increments that are less than 1" for quick reading.
