Stainless Steel Machinist Ruler 24 with 16R Graduations

These machinist rulers, crafted by Shinwa in Japan, epitomize precision and durability. Shinwa, a foremost manufacturer of measuring instruments in Japan, is setting a global standard with these rulers. Each ruler adheres strictly to the Japanese Industrial Standards (JIS B7516 Grade 1), ensuring consistency across material composition, hardness, length, thickness, end squareness, finish, flatness, and straightness.

Featuring 16R markings, one side of the ruler displays graduations in 1/32nd and 1/64th increments, while the reverse side showcases 1/50th and 100th markings. These markings, created through precision photo-etching and filled in black, offer superb readability that remains intact over extended use.

Constructed from SUS420J2 stainless steel, hardened to HRC-40 and finished with a smooth, hard, non-glare chrome coating, these rulers are highly resistant to scratches and corrosion. This chrome finish not only enhances durability but also minimizes glare, ensuring clear visibility even under bright lighting conditions.

The ruler's edges are meticulously ground straight and smoothed to perfection. This precision allows for effortless scribing with pencils or marking knives, eliminating any resistance. Additionally, the ruler ends are ground square to an exceptional tolerance of within 0.001 inches.

Available in various sizes to suit different needs, the 6-inch ruler measures 3/4 inch wide by 0.032 inches thick, the 12-inch ruler measures 1.25 inches wide by 0.040 inches thick, the 24-inch ruler measures 1.25 inches wide by 0.040 inches thick, and the 36-inch ruler measures 1.25 inches wide by 0.040 inches thick. Each ruler is accompanied by a vinyl sleeve for protection when not in use.
