Measured the flatness using a calibrated CMM and over 1500 points on the machined surface. Flatness of the straight edge is advertised as <0.001", measured value was less than a third of that at 0.0003".Can't beat it for the money.
This is a quality straightedge that will last you far longer than a lifetime if you take care of it and it doesn’t sprout legs and walk away like many of my quality tools have over the years. I purchased several in different lengths.
I bought this to occasionally check engines and heads. I had doubts with such an inexpensive tool, so I had my calibration lab check to verify straightness. They found only 0.0004" total indicator movement over the entire flat surface. Very pleased with these results, and recommend to anybody looking for an inexpensive precision straight edge.
Note: This is an aluminum tool, so it will not scratch or mar iron or steel; however, it is easy to damage and will wear quickly with repeated use, requiring resurfacing.
I used this to verify straightness of a motor head deck surface. Definitely did the trick. It was packaged in a cardboard tube, similarly to poster tunes, but .25" thick. I keep it in there still for safe storage. Would buy again!

The manufactures holding tolerance is close enough to set up your basic miter Saw. Inspection of table saw top and so on. It’s not a super accurate Professional Machining type straight edge.
