A. Steel Cups For Magnets
These cups are counterbored to fit the rare-earth magnets we sell. The cup for the 1/4" magnet has a ridged outer surface for a press fit into a 3/8" x 1/4" deep hole. The larger cups can be screweddirectly to the face of the workpiece or flush mounted in a counterbored hole. The 1/2" and 5/8" cups are 1/4" thick and countersunk for a #4 flat-head screw; the 7/8" and 1-1/8" cups are 9/32" thick and countersunk for a #10 screw (to restrain the larger magnets' greater attraction). Sizes stated below are the outside diameter (O.D.) and the counterbore size to fit our rare-earth magnets (sold separately). Zinc-plated steel. Sold individually.

B. Steel Washers For Magnets
The three smaller washer sizes are 1/8" thick and have a 1/8" dia. hole countersunk for a #4 screw, while the two larger sizes are 5/32" thick and countersunk for a #10 screw. The outside diameters (O.D.) are slightly undersize and match their respectivecup, so that the same size of drill bit can be used for counterboring both when you want them flush mounted. Sold individually.
