China Neodymium And Ferrite Magnets Manufacturer & Supplier 
15mm countersunk magnet typically refers to a magnet with a diameter or width of 15mm and screw holes. This type of magnet is widely used in applications that require magnets to be fixed to other materials. Usually made of neodymium, The following are four popular 15mm countersunk magnets.
15mm Round Countersunk Magnet
This is the most common type, also known as a countersunk magnet ring. The countersunk hole is usually located in the center of the round magnet, with common sizes being M3 and M4. It is suitable for general magnetic attraction needs, and the hole diameter and position can be customized according to requirements.
The accompanying image shows a circular countersunk magnet with a diameter of 15 mm, a thickness of 5 mm, and a hole diameter of 4 mm.
15mm Square Countersunk Hole magnets
A square countersunk magnet with a side length of 15mm. The diameter of the hole is generally between 3mm and 8mm. The hole diameter and position can be customized according to customer requirements. It is typically used in applications that require stable and uniform contact.
15mm Rectangular Countersunk Magnets
A 15mm rectangular countersunk magnet refers to a rectangular magnet with a length of 15mm that has one or more countersunk holes drilled into its surface. The rectangular design provides a wider contact area, making it suitable for applications requiring greater magnetic force. Customers can select the appropriate hole diameter based on their installation requirements.

15mm Pot Shaped Countersunk Magnets
The 15mm countersunk pot-shaped magnet is a magnet shaped like a pot, also known as a neodymium component. It features a stainless steel sleeve with an outer diameter of 15mm, a central hole, and a concave bottom. It is characterized by strong pulling force and resistance to breakage, making it widely used in various applications requiring magnetic fixation.
The above are four types of popular 15mm countersunk magnets. These magnets are mainly used for strong adsorption or stable fixation, and are commonly used in industrial equipment, home appliances, automotive accessories, and other scenarios.
