Both blade and beam are made to be hardened, ground, and lapped, resulting in parallelism and straightness. The Starrett #20-3 Master Precision Square measures 3" (75mm) in blade length and 2-3/8" (60mm) in beam length. Please note that this precision square does not come with original packaging. This tool is perfect for checking squareness with accuracy up to .0001" (0.0025mm) every 6" (150mm).
