Neodymium Rubber Coated Magnet with Internal Thread (NRBC Series)
It is a heavy-duty encapsulated pot magnet built with high-strength neodymium (NdFeB) magnet core, fully covered by soft protective rubber. A recessed female threaded bush is embedded at the center backside instead of an exposed bolt. Users can screw bolts into this internal thread from the rear to attach brackets, fixtures, lamps and sensors. Different from external thread types, this magnet allows flush, hidden installation without protruding studs.

Core Advantages & Main Application Fields
• Advantages
1. No Surface Scratches
The elastic rubber outer layer eliminates direct hard metal contact. It will not scratch painted panels, stainless steel, aluminum, car bodies or polished workpieces after repeated adsorption and removal.
2. Anti-slip & Vibration-resistant
High-friction rubber prevents sliding on vertical metal surfaces even under long-term vibration, ideal for suspended equipment and industrial fixtures.
3. Waterproof & Anti-rust
Sealed rubber shell blocks water splash, humidity and salt mist, preventing the neodymium core from oxidation and rust, suitable for damp workshops and marine temporary fittings.
4. Shock Absorption & Low Noise
Rubber cushions impact when attaching to metal, avoiding cracking of fragile NdFeB core and reducing collision noise during installation.
5. Hidden Flush Mounting
Since there is no protruding threaded stud, the magnet can be installed flat against mounting plates. It saves space, avoids protruding obstacles and looks neat, perfect for compact equipment, display racks and concealed fixing structures.
6. Simple Installation
Align the bolt with the internal thread on the back and screw it in directly to fasten all kinds of brackets; no extra nuts required for assembly.
• Applications
1. Machinery & Workshop: Fix measuring tools, sensor supports, positioning jigs on machine frames
2. Automotive: Concealed mounting of inspection lights, cameras and warning tags on vehicle shells
3. Marine & Hardware: Salt-resistant temporary holders on boats and iron cabinets
4. Advertising & Display: Hidden hanging of light boxes, acrylic signs and retail display shelves
5. Household & Furniture: Concealed magnetic brackets, lamp holders and storage racks
