Magnetic holders with internal threads and neodymium magnets
Neodymium magnets with internal threads
Magnetic holders with internal threads consist of magnets housed in a casing available in one of three finishes: nickel-plated (Ni), zinc-plated (Zn), or chrome-plated (Cr). The housing has a threaded hole in the center, which makes installation easier. Thanks to their housing, magnetic holders with internal threads are impact-resistant, and their holding force is increased because the force is concentrated on one side neodymium magnet.
What diameters of neodymium magnetic holders with internal threads are available??
Our neodymium magnets with internal threads are available in diameters ranging from 6 mm to 85 mm, while the available thread sizes are M3 (3 mm), M4 (4 mm), M5 (5 mm), M6 (6 mm), M8 (8 mm), M10 (10 mm), and M12 (12 mm). Thanks to our wide selection, everyone can find the neodymium magnets with internal threads that they need. You can also purchase bolts and screws for fastening purposes at our store neodymium magnetic holders.
Frequently Asked Questions and Answers About Magnets with Internal Threads
What are the best uses for neodymium magnets with internal threads??
Neodymium magnets with internal threads are extremely versatile fasteners that are used wherever a strong yet non-invasive attachment to steel surfaces is required. Thanks to the threaded hole, you can screw any screw, pin, or hook into them, making them the perfect choice for mounting lamps, information signs, sensors, and exhibition displays. Their design allows for repeated installation and removal without drilling holes in the surface, which is essential in modern industry, retail, and DIY workshops.
How to Choose the Right Magnetic Holders with Internal Threads for a Specific Task?
When choosing the right clamp, you should primarily consider the required load capacity and the thread size, which must be compatible with the component you plan to mount. It is important to note that the stated holding force applies to the perpendicular removal of the magnet from thick, smooth steel; therefore, when mounted on a wall or on thin sheet metal, the actual holding force will be lower. It is also important to consider the outer diameter of the housing, as a larger contact area with the substrate ensures better stability of the entire mounting, especially under shear loads.
Are magnetic holders with a threaded hole weather-resistant??
Standard neodymium magnetic holders with internal threads are housed in a steel casing coated with a layer of zinc, nickel, or chrome, which provides them with good protection against corrosion when used indoors. However, if the mount will be constantly exposed to rain, moisture, or road salt, it’s worth considering models with an additional rubber coating that completely insulates the magnet and protects painted surfaces from scratches. Proper maintenance and avoiding use at temperatures exceeding 80 degrees Celsius will ensure that the handle retains its magnetic properties for many years of use.
Why Is a Steel Housing So Important in Magnets with Internal Threads??
The steel casing, in which the neodymium magnet is embedded, serves two key functions that give these holders an advantage over ordinary magnets without a casing. First, it protects the brittle neodymium sintered material from cracking when it strikes a metal surface with great force, which significantly extends the component's service life. Second, the housing creates a special magnetic circuit that redirects the magnetic field from the top of the magnet to its bottom, resulting in an almost twofold increase in magnetic force upon contact with metal, ensuring an exceptionally secure and stable connection.
What are the advantages of an internal thread compared to models with a fixed screw??
The main advantage of neodymium magnets with internal threads is their tremendous flexibility and the ability to perfectly match the length and type of screw to a specific installation need. Unlike models with a protruding shank, the version with a hole allows the screw head to be concealed or decorative caps to be used, which enhances the aesthetic appeal of advertising or lighting installations. Furthermore, if the external thread on the fastened component is damaged, the magnet itself remains intact and ready for reuse with a new screw, making it a more economical and durable solution over the long term.
