6 Inch Digital Caliper

Pretty dang accurate for what we use them for: measuring spindles, screw sizes, drill bits for predrilling, holes, and hardware thickness.

They switch between fractions, decimal inches, and metric

Keep them somewhere you will actually use them.  They are not so fragile or expensive that you will hide them from your coworkers. And if someone drops them, you will not completely freak out.

Stainless steel with LCD screen. Includes protective case and batteries. Ready to go out of the box.
