Matched Pair 25mm x 3mm Countersunk Ring Magnets with Screws

Matched pair of countersunk neodymium magnets, designed to align north-to-south for maximum holding force. The countersunk faces are precision matched to sit flush together, making them ideal for cupboard latches, door closures and concealed fixing applications. Supplied with mounting screws.

1 x Countersunk North Magnet
1 x Countersunk South Magnet
2 x 6G x 18mm Screws

Dimensions:
The dimensions of the product are measured in metric units, with an approximate "tolerance" (manufacturing margin of error) of +/- 0.05mm 
Diameter: 25mm (D)
Height: 3mm (H)
Countersunk Hole: 8.4mm (D1)
Through Hole: 4.2mm (D2)



Pull Strength: 5kg*
The approximate force (in metric units) required to remove a magnet from industry-standard 3mm thick mild steel. These "strengths" are measured using mathematical calculations, and should be used as a general guide only.    
*When used magnet-to-magnet (north to south), holding force is typically stronger than the listed pull strength to steel. As a general guide, expect around 10–30% higher holding force compared to mounting against 3mm mild steel, depending on alignment and surface gap.

Direction of Magnetism: "Axially"
Magnetised (top to bottom) thru 3mm height. The axis through which a product is magnetised. 

Grade: N42
In permanent magnets, the grade refers to the materials used in the production process. Material "grades" range from low end (weaker) to high end (stronger). See more about magnet grades at our Help Centre.     

Features:
- Powerful Rare Earth (Neodymium) permanent magnet.
- Countersunk SOUTH face to match to the NORTH version for latching 
- High gloss Nickel coating, for protection against corrosion.
- Maximum operating temperature 80°C / 100°C
