Precision inspection squares

Precision squares are instruments used to check perpendicularity, flatness, and angular accuracy in mechanical machining and quality control operations. They are used in workshops, metrology rooms, and production departments to check the geometric accuracy of machined parts, equipment, and reference surfaces.

Available in different configurations, squares can be plain, with base, bevelled, or knife-edge versions, with models made of dimensionally stable steel or stainless steel. Stainless steel squares are particularly appreciated in environments where greater corrosion resistance is required, while bevelled versions help reduce optical errors during inspection.

Precision squares with base are often used to check squareness and parallelism during mechanical assembly, dimensional inspection, and fabrication work. Precision squares are also used as references for geometric checks on machine tools, workbenches, and measuring systems.

The range includes models for general industrial use and versions dedicated to high-accuracy metrology inspection. Different sizes and configurations are available to suit both production requirements and more accurate quality control checks.

The available square sizes allow checks to be carried out on small and large components while maintaining high geometric stability and long-term reliability. Steel squares are used every day to check the correct execution of machining, welding, assembly, and marking operations.

Thanks to their simple construction and robustness, squares remain essential instruments in measuring and geometric inspection processes, helping improve the quality and conformity of mechanical machining.
