For a few years we’ve been experimenting with different stainless-steel plate stocks, trying to find one we could machine as consistently as the cast-and-ground tool plate aluminum we use in our Precision Squares. When we found one, we put many of the features of our aluminum squares into the new stainless-steel design, and then added a few more, too. The result is a versatile square, ideal for project lay out work, material and assembly checking and machine set up.
