2pk Round Neodymium Magnets with Countersunk Hole, 70 LBS Pulling Force, 1.65" D

Description

These round base rare-earth neodymium (NdFeB) cup magnets are made with an A3 steel casing and coated with Nickel-Copper-Nickel to be the strongest type of permanent magnet available.
The countersunk hole allows many types of mounting applications including hook, knob, or eyebolt. Screw it into a wall to hold tools, or position and hold lights, signs, and more. This type of magnet is also perfect for magnet fishing and retrieving applications.
Please note that holding power of 70 lbs is tested on unpainted horizontal ½” steel plate. Mounting on a vertical or painted surface will reduce holding power by up to 70%.

THESE RARE-EARTH MAGNETS ARE EXTREMELY STRONG AND AS SUCH SHOULD BE KEPT OUT OF REACH OF CHILDREN. RARE-EARTH MAGNETS ARE NOT TOYS. SECURE MAGNETS WHEN UNATTENDED.
Children should not be allowed to handle or play with rare-earth magnets. Rare-Earth magnets are fragile and can break easily. These magnets are powerful and can accelerate at high speeds toward each other and toward ferrous material. When these magnets come together quickly, they can shatter and break sending particles at speed. These magnets can also pinch strongly if allowed to come together against the skin. You should always wear gloves and eye protection when handling large magnets.
