Rubber coated neodymium pot magnets are strong and durable magnetic assemblies with a threaded center hole (internal female thread) and
protective rubber coating. Made with N35 /N42 neodymium disc magnets attached to a flat steel disc and coated with black isoprene rubber
which leaves no marks and prevents surfaces from scratching. The protective rubber coating protects magnets from corrosion or oxidation for
 sustained use in outdoor environments. It also prevents magnets from chipping easily and provides more slip-resistance than other types of
coated or uncoated magnets.

NdFeB Magnets are axially magnetized (through the thickness).
TPE Black Rubber Coating is approx. 0.02” thick.
