Countersunk magnet, also known as a counterbore magnet, is a powerful counterbore magnet that is installed and fixed in the desired position through screws. The size of a countersunk hole magnet is generally represented by a large D for diameter, d1 for countersunk hole diameter, d2 for straight hole inner diameter, and H for thickness (height).

Speaking of this type of magnet, do you really feel unfamiliar? Let me give a few examples now to see if you are familiar with it. There are some large screws on the toys of children at home, especially those robots. Although it may seem easy to unscrew them, it is really difficult to handle them in practice. It feels like something is sucking on them, This is a special type of circular counterbore magnet: screw hole magnet.

Our company can customize any size and performance of neodymium iron boron countersunk hole strong magnets, high-temperature resistant countersunk hole magnets, square rectangular double countersunk hole magnets, circular countersunk hole magnets, etc. If you need a quotation or sample of the magnet, please feel free to come and provide us with pictures and samples.

This powerful magnet coated with colored zinc

Color zinc magnet, also known as a strong magnet coated with color zinc neodymium iron boron, has a five color surface. Perhaps because there are relatively few electroplating manufacturers that produce this coating due to the price, it is troublesome. Therefore, we usually see rare neodymium iron boron strong magnets that produce this coating. I have been in contact with the magnet industry for some time, and there are generally no customer requirements for this coating on the surface. Most of them use galvanized nickel plating.
