Steel 6 Inch (150mm) Ruler

A reliable bench reference for everyday measurement tasks, this stainless steel ruler is an essential tool for jewelers, metalsmiths, and watchmakers. One side features dual-scale graduations running to 6 inches and 150mm, making it easy to switch between imperial and metric readings without changing tools. Flip it over and you have a compact reference chart imprinted directly on the steel—covering inch-to-metric conversions, fraction-to-decimal equivalents, Tap Drill data, and W.W. UNF threading information. At 0.80mm thick, it lies flat on the bench without flexing under light pressure.
