These block magnets are 1.000 inch (25.4mm) long, 0.250 inch (6.4mm) wide and 0.100 inch (2.5mm) 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 5 lbs. Maximum working temperature is 176 F (80 C).
