Rectangle pot magnets, rectangular neodymium holding magnets, bar pot magnets with countersunk holes

Rectangle Pot Magnets Single Double Countersunk Hole Neodymium Holding Magnets for Industrial Mounting

If you are searching for reliable heavy duty magnetic mounting solutions, our rectangle pot magnets will bring stable and powerful holding performance for your work. Different from ordinary block neodymium magnets, these bar shaped pot magnets adopt thick steel pot shell to wrap the magnet core. This special structure greatly optimizes magnetic field distribution, gathering most magnetic energy on working surface to achieve much stronger attraction force. Meanwhile the metal shell provides solid physical protection, effectively preventing magnet cracking, chipping and collision damage during installation and daily usage.

We supply two mainstream structural versions for selection. Single countersunk hole rectangle pot magnets are compact for limited installation space, while double countersunk hole models provide firmer fixation to avoid rotation or shifting under vibration environment. All mounting holes are standard 90 degree countersink design, allowing flat head screws to sit flush without protruding, keeping surface neat and avoiding scratch risk. Nickel surface finish brings good rust resistance for indoor working conditions.

Rich ready stock sizes cover small lightweight units to heavy load options. The smallest model delivers 4kg pull force, and maximum stock size can reach 40kg holding capacity. Each specification comes with complete dimension data including length width height hole size and net weight for your quick reference during project design. Beyond standard inventory items, we accept custom development. You can adjust overall dimension, hole quantity, hole position, magnet grade and surface coating to match your unique equipment or fixture requirements.

These rectangle pot magnets are widely adopted across multiple industries. Mechanical equipment manufacturers use them for position fixing and component locating. Workshop operators apply them for tool temporary holding and part clamping. Automation hardware, cabinet assembly, welding fixture and DIY engineering projects also frequently pick these holding magnets. It works well when attaching onto steel ferrous surfaces. Please note pull force data is tested under ideal smooth thick steel plate condition. Actual holding performance will vary according to surface flatness, material thickness and gap.

Strict quality inspection is implemented before shipment. Every batch will go through pull force testing, dimension checking and surface appearance screening. We support small batch trial order and large volume wholesale. Fast lead time for standard stock items. Our technical team can offer parameter suggestion to help you select proper magnet size based on your load demand and installation space.
