It's time to add Grip to your Measuring Tools with our brand new Precision Squares with our Patented Flex Grip.These Precision Squares are made with 301 Full Hard Stainless Steel for overall durability. We etch, then engrave each marking on our laser system to ensure each mark stands the wear and tear of everyday use.Patented Flex Tabs are used to grip to virtually any surface softer than the steel itself. That means no more slipping when marking or scribing your workpiece, metal, paper, and more.Scribing notches are a must and are spaced out every 1/16th for perfect, accurate lines across your entire project.Last but not least, each square has a balancing tab which is easy to engage, locks into place and allows you to balance and scribe right across your work piece with ease. Unlock it when not needed for your application.Tolerance Request: The engraving is within 0.004"" and we set every square to within 0.
