This 18in x 24in Grade B granite surface plate provides a stable, flat reference plane for inspection and layout tasks. Grade B plates are specified for general purpose shop work where high precision is required but not the absolute flatness of a Grade A plate. Granite construction offers thermal stability and corrosion resistance, essential for maintaining accuracy over time in varied shop environments.
Used in machine shops, inspection departments, and fabrication facilities, this surface plate supports precision measurement with height gages, indicators, and comparators. Granite maintains its flatness and dimensional stability well over years of use, resisting nicks and burrs that can compromise accuracy in metal plates.
