Description

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.

Features

  • Dual-scale graduations: inches (to 6") and metric (to 150mm) on one side
  • Reverse side imprinted with inch-to-metric conversion table
  • Fraction-to-decimal equivalent reference chart on reverse
  • Tap Drill information imprinted on reverse side
  • W.W. UNF threading reference imprinted on reverse side
  • Constructed from stainless steel at 0.80mm thickness
  • Flat profile stays stable on the bench surface
