15mm Circular Sinking Hole Neodymium Iron Boron Magnet for Mounting and Craft Use

These neodymium iron boron magnets are designed for practical applications where a secure, flush-mounted hold is required. The circular sinking hole allows for easy attachment using screws or adhesive, making them ideal for enclosures, jigs, signs, or craft projects. With a density of 7.5 and an operating temperature of 80°C, they offer consistent performance in typical indoor and light industrial environments. Each magnet is sold individually, giving you flexibility to choose the exact thickness needed.

Features and Construction

The magnets are built from neodymium iron boron, a material known for its high magnetic strength relative to size. The circular sinking hole design enables a clean, low-profile installation that sits flush with the surface.

Material and Build

Manufactured from neodymium iron boron (NdFeB), these magnets provide strong magnetic properties in a compact form. The material is brittle, so careful handling is advised to avoid chipping or cracking during installation. The surface finish is typical for this type of magnet, suitable for general-purpose use.

Size and Practical Fit

Each magnet has a diameter of 15mm. Thickness options of 3mm, 4mm, and 5mm are available, allowing you to match the holding strength and profile to your specific application. The sinking hole in the centre accommodates a screw or adhesive for mounting.

Uses and Placement

These magnets are suitable for a range of tasks where a reliable magnetic hold is needed, and the flush-mount design minimises obstruction. Their simple form makes them easy to incorporate into various setups.

Industrial and Workshop Use

Ideal for securing parts in jigs, holding tools on metal surfaces, or fastening enclosures and panels. The consistent magnetic performance supports repeated use in workshop environments.

Everyday Home and Craft Use

Use in DIY projects to create magnetic closures for boxes, frames, or display boards. The flush profile ensures a neat finish, and the choice of thickness lets you adjust strength as needed.

Benefits and Buying Value

These magnets offer a straightforward way to add magnetic holding to your project without complex installation. Sold individually, you can purchase exactly the quantity and sizes you need.

Simple Mounting

The sinking hole allows for quick attachment with a common screw or a dab of adhesive. No special tools are required, saving time during assembly.

Flexible Sizing

With three thickness options from the same 15mm diameter, you can select the right balance of holding force and profile height for different applications. Additional sizes are available by consulting customer service.
