These spring-tempered rules are 3/64" thick (1.2mm) and have finely ground edges, making them ideal for marking or scribing. They have a no-glare satin chrome finish that provides better rust resistance than polished steel. Graduations are machine-divided (not photoengraved) for uniformity of line width and depth. All are graduated in the 4R style (with increments in 8ths, 16ths, 32nds and 64ths).
