SPECIFICATIONSThese rod magnets are 0.500 inch (12.7mm) diameter and 0.500 inch (12.7mm) long. They are magnetized through the length. 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 19 lbs. Maximum working temperature is 176 F (80 C).
