Description
Dasqua 8500-3020 300 x 200 x 60 mm Grade A Granite Surface Plate provides a highly precise and stable work surface for measuring, layout, and inspection tasks. The top surface is precision ground to achieve a flatness accuracy of ±0.0001″, making it suitable for professional workshops and quality control applications. Classified as Grade A (Grade 0), this granite plate meets or exceeds Federal Specification GGG-P-463C and comes with a certificate of inspection. Its non-magnetic and non-conductive properties, along with hardness exceeding steel, ensure it does not nick or burr, providing a durable and reliable measurement surface.
