Mr. Pen Machinist Ruler Set, 12-Inch Stainless Steel, 2-Pack

Choosing a ruler for quick, everyday measurements is different from choosing one for detailed technical work. The Mr. Pen machinist ruler set is aimed at the latter, with several imperial graduation scales on each ruler.

Each ruler is 12 inches long, and the set includes two. That makes it practical to keep one at a drafting or work area and another elsewhere, or to have a spare available.

The main distinction is the markings: one side uses 1/32- and 1/64-inch graduations, while the other uses 1/10- and 1/100-inch graduations. This is a useful format when a task calls for different ways to read imperial measurements.

Size & fit

These are 12-inch rulers, so they suit measurements and layouts that fit within that length. For example, someone working through a drawing or marking a piece of material could use the finer graduations for closer readings, then switch to the decimal-inch side when that scale is more convenient. The two-ruler pack also gives you the option to keep a ruler in two work areas rather than move a single one back and forth.

They are stainless steel and silver-colored. The listing identifies the rulers as imperial, so they are best suited to work where inch-based markings are the required format. If your projects call for metric markings, these specifications do not indicate that this set includes them.

Pros

The range of graduations is the main reason to choose this set over a basic ruler with fewer marking options. Having fractional-inch and decimal-inch scales on opposite sides gives you flexibility for drafting, engineering-related tasks, carpentry, schoolwork, and office measurements, without changing tools for each scale.

Stainless steel provides a metal alternative to a basic plastic ruler, and the two-piece pack can be useful when measurements are part of more than one routine. You’ll appreciate it if you want a straightforward imperial measuring tool with fine markings and a second ruler ready to use. You may want to skip it if your work depends on metric graduations, which are not listed here.

Questions before you buy

How many rulers are included? The set contains two 12-inch rulers.

What measurements are marked? One side has 1/32- and 1/64-inch graduations, the other has 1/10- and 1/100-inch graduations.

Is this a metric ruler? The product is described as imperial, and the listed markings are in inches. Metric graduations are not specified.

Is it worth it?

This set makes sense when the useful feature is not just having a ruler, but having multiple imperial scales available on the same tool. Compared with buying a simpler ruler for occasional, general measurements, the Mr. Pen set is more relevant to work that benefits from finer fractional readings or decimal-inch markings. The two-ruler format can also suit separate workspaces or shared use.

Its appeal depends on those specific needs: the listing does not describe metric markings, and the rulers are each 12 inches long. Choose it for a compact pair of stainless steel rulers with several inch-based graduation styles, look for a different format if your usual measurements require metric units or a longer measuring range.
