This size is also available in grade N42 with our standard Nickel plating as part number B444, in grade N52 as part number B444-N52 and with a 1/16" hole through the center as part number B444-1.
Note: Our "Black Nickel" plating is achieved by adding a special tint during the nickel plating process. The resulting color is not black. The appearance of these magnets is best described as grey, charcoal or gunmetal. Due to this unique process, slight variation in color may occur from order to order.
