36 Stainless Steel Machinist Ruler with English/Metric Graduations

The Shinwa machinist ruler is a meticulously crafted measuring tool made in Japan. Shinwa, the leading manufacturer of measuring tools in Japan, is quickly becoming a global benchmark. All of their rulers are manufactured to strict Japanese Industrial Standards (JIS B7516 Grade 1) for material consistency, hardness, length, thickness, end squareness, finish, flatness, and straightness.

This particular ruler features both English and Metric markings, with 1/32nd and 1/64th graduations on one side, and millimeter and .5mm marks on the reverse. The super-fine graduation marks have been precision photo-etched and then black-filled for exceptional readability. These markings are designed to withstand years of use without fading or wear.

The ruler is constructed from SUS420J2 stainless steel, hardened to HRC-40, and coated with a smooth, hard, non-glare chrome. This chrome finish not only makes the rule resistant to scratches and corrosion but also dramatically reduces glare, enhancing readability in bright-light conditions.

The edges of the ruler have been expertly ground straight and then smoothed, ensuring a seamless scribing experience when used with a pencil or marking knife. The ends are ground square to within an impressive 0.001" tolerance.

The overall dimensions of this Shinwa machinist ruler are 36 inches long, 1.25 inches wide, and 0.040 inches thick. The ruler comes with a protective vinyl sleeve, ensuring it remains in pristine condition when not in use.

In summary, this Shinwa machinist ruler is a superior measuring tool crafted with uncompromising attention to detail. Its precision-engineered features, durable construction, and exceptional readability make it an invaluable asset for any workshop or worksite.
