Product Description

Sintered NdFeB high-strength magnets with precision tapered countersunk screw holes. Available in round and block shapes with customizable single-hole and double-hole structures. Compatible with M3, M4, M5, M6 and other standard countersunk screws. After installation, the screw head is fully embedded inside the magnet, ensuring a completely flat and smooth surface for precision assembly.

Core Advantages

1. Ultra Strong Magnetic Force

Made of rare-earth permanent magnet material. It provides far stronger adsorption force than ordinary ferrite magnets under the same volume. Regular grades include N35, N38 and N52 with stable and powerful magnetism.

2. Flush & Firm Installation

The embedded screw design ensures no protrusion on the magnet surface. It will not scratch workpieces or interfere with mechanical movement, perfectly suitable for precision equipment assembly.

Corrosion Resistance &amp; Durability

Surface treated with nickel plating or nickel-copper-nickel multi-layer coating, effectively anti-rust and anti-oxidation for long service life.

4. Easy Disassembly & Anti-loosening

No glue required. Mechanical screw locking makes the magnet anti-vibration and non-loosening, supporting repeated disassembly and maintenance.

Specifications & Structure

Round Magnets: Customizable outer diameter D, thickness T and countersunk hole size;

Block Magnets: Custom length, width and thickness, with middle holes or double-end holes optional;

Magnetization: Standard axial magnetization. Magnetic force concentrates on the front and back adsorption surfaces for stronger suction.

Applications

Widely used in tooling fixtures, mechanical positioning, equipment magnetic latches, cabinet magnetic suction, mold fixing, tool storage, advertising display stands, automation equipment, sensor fixation, DIY equipment modification and other industrial fields.
