Benchmark Tools 466675 Rigid 4R 6 Inch Machinist Rule with 1/8, 1/16, 1/32 and 1/64 Markings Tempered Stainless Steel Non-Glare Black Chrome Finish Conforms to EEC-1 Accuracy Standards (1)

A good, quality machinist rule is an indispensable tool used by machinists, woodworkers, architects, draftsman, scientists, students, DIYers and more. When used correctly, a good steel rule is a surprisingly accurate measuring device. These rules are made from Japanese rust-resistant stainless steel that has been tempered creating a measuring tool that can flex if needed but will snap back straight. The edges and ends have been ground parallel, straight, smooth and square. Graduations are produced via a photoengraving process creating very consistent and accurate markings with uniform line widths. Once etched, graduations are white filled for maximal readability. Graduation are etched and not printed so will not wear off with prolonged use. Graduations conform to strict international EEC 1 Accuracy Standards, i.e. +/- 0.2 mm at 20 Degrees C for 1000 mm Rule. 4R graduation marks feature quick-reading 32nds and 64ths on one side and 8ths and 16ths on the reverse. Finish is black chrome. Black chrome finish provides scratch and corrosion resistance and maximizes readability by achieving a zero-glare, high-contrast, EZ read finish that enhances readability in both low and bright light conditions. Each rule comes in vinyl storage pouch. These are well made rules and will provide years of reliable service in any shop, studio, clinic, lab, classroom or home environment.
