Benchmark Tools Rigid 4R 12 Inch Machinist Rule

A good quality machinist rule is an essential tool used by a variety of professionals and DIY enthusiasts such as machinists, woodworkers, architects, draftsmen, scientists, students, and more. When used correctly, a good steel rule is an incredibly accurate measuring device. These rules are made from tempered Japanese stainless steel that is resistant to rust, allowing the measuring tool to flex when necessary but still maintain its straight shape. The edges and ends are meticulously ground to be parallel, straight, smooth, and square. Graduations are created using a photoengraving process to ensure consistent and accurate markings with uniform line widths. The graduations are then filled in with white for maximum readability and durability against prolonged use. They conform to strict international EEC 1 Accuracy Standards, ensuring precision with a tolerance of +/- 0.2 mm at 20 degrees Celsius for a 1000 mm rule. The 4R graduation marks provide quick-reading measurements in 32nds and 64ths on one side, and 8ths and 16ths on the reverse side. The black chrome finish not only provides scratch and corrosion resistance but also enhances readability with a zero-glare, high-contrast, EZ read finish, making it suitable for various lighting conditions. Each rule comes with a vinyl storage pouch for added protection. These well-made 12" rigid machinist rules with 4R markings are designed to withstand years of reliable service in any work environment. Additionally, the overall size of the rule is 12 inches long, 1 inch wide, and .040 inches thick.
