Internal Threaded Cup Magnets
Description
Reviews
As a leading NdFeB pot magnet manufacturer in China, MAG SPRING offers high-performance Internal Threaded Cup Magnets (also known as Neodymium Pot Magnets with Inner Thread or Female Threaded Cup Magnets). These powerful mounting magnets feature a steel cup housing with an internal threaded hole, providing strong holding force, easy installation with screws or bolts, and reliable performance for various industrial and commercial applications.
Product Overview
Internal Threaded Cup Magnets consist of a high-performance rare earth magnet encased in a durable steel cup with an internal (female) thread. The steel pot concentrates the magnetic field on one side, significantly increasing holding force while protecting the magnet and allowing easy mounting via screws, eyebolts, or hooks. They are ideal for secure fixing, hanging, lifting, and positioning in construction, engineering, automotive, workshops, offices, warehouses, and more.
At MAG SPRING, we provide customizable internal threaded cup magnets in various sizes, materials (NdFeB, SmCo, Ferrite), coatings, and thread specifications (M4, M5, M6, M8, M10, etc.) to meet your exact requirements.
