NSN0732
Rare-Earth Disc Magnets,
0.375 in. Diameter x 0.0625 in. Thick,
40-Count

SPECIFICATIONS +
These disc magnets are 0.375 inch (9.5mm) diameter and 0.063 inch
(1.6mm) thick. They are magnetized through the thickness. They
are composed of grade 40 neodymium iron boron magnetic material
and are plated in nickel-copper-nickel for a shiny corrosion
resistant finish. Their individual pull force is approximately 2
lbs. Max Working Temperature - 176 F (80 C).
