Mount your NEMA 23 motors easily with these motor mount plates. Provides 1.500" motor mount bore, NEMA 23 bolt hole pattern for use with #10 machine screws and nuts, and quarter-inch mount holes for mounting the plate to your desired application. Oversized counterbores on one side for the motor mount holes allow the use of nuts and screws to secure the motor to the plate. The oversize counterbores provide enough clearance to fit a standard #10-sized nut as well as additional clearance so that your 3/8" or 10mm (1/4" drive) sockets will fit into the counterbore to tighten and loosen the nuts. Using the proper length screw, this oversize counterbore system allows the nut and screw to remain below the surface of the plate and will allow this plate to be mounted flush with a mating surface.
