**Precision Without Compromise: The Stainless-Steel Ruler**
Measure once, cut once. This precision-milled stainless-steel ruler is built for makers, machinists, engineers, and designers who refuse to settle for "close enough."
Each ruler is CNC-milled from a single bar of premium 304 stainless steel, then finished with a satin brushed surface that resists glare and fingerprints. The graduations are etched deep rather than printed, so they will never fade, smudge, or wear away, even after years of daily use in the shop, studio, or lab.
Markings are accurate to within ±0.01 inch, with clear imperial and metric scales on opposite edges. Fine 1/64" and 0.5 mm increments make detailed layout work effortless, while bold numerals keep readings fast and error-free.
The ruler's perfectly flat, square-ground edges make it a dependable straightedge for scribing, marking, and trimming. A cork backing prevents slipping on any surface, and a hanging hole at one end keeps it within easy reach at your bench.
Corrosion-resistant, durable, and surprisingly light, this ruler is a tool you'll pass down rather than replace.
**Features:** - 12-inch / 300 mm length - Etched dual scales - Cork non-slip back - Rust-resistant 304 stainless steel
Precision you can trust, for life.

Stainless-Steel Ruler: Accuracy Without Compromise
Measure once, cut once. This milled stainless-steel ruler was created for makers, machinists, engineers and designers that know when good is almost not enough.
CNC-milled from a single bar of high grade 304 stainless steel, each ruler is then finished with a satin brushed finish that deflects glare and resists prints. The graduations are not printed but engraved deep, so will never rub off, wear away or otherwise become illegible even after years of exposure to the rigours of day-to-day use in shop, studio or lab.
In addition to the markings being ±0.01 inch accurate, scales are shown in clear imperial and metric measurements on opposite edges. Fine 1/64″ and 0.5 mm increments make detailed layout work a breeze, with easy-to-read bold numerals for fast readings free from mistake.
The ruler's perfectly flat edges ground square to 90 degrees makes it a straightedge that is easy to rely on for scribing, marking, and trimming. At one end there's a hanging hole for letting it dangle close by at your workbench, and it's backed with cork to avoid slipping on any surface.
This rule is corrosion-resistant, super sturdy, and floats in water - a tool you'll keep forever instead of replacing.
