The Groz Steel Precision Squares are hardened steel to ensure accuracy and straight lines for precision layout, machine setups, and verifying straight lines, particularly in woodworking. The hardened spring steel blades are permanently fixed to the stock by means of tapered self-locking rivets to stay rigid. The blades and stock of these Precision Squares are precisely ground to ensure straightness and parallelism and the working edges of the blades are lapped for enhanced accuracy. The groove on the inner corner of the stock aids in the clearance of burrs or dirt to easily make accurate measurements.

These precision squares have an internal and external squareness as per BS 939 Grade B*.

Available in 2”, 3”, 4”, and 6” blade lengths.
