CMS Magnetics - (2-Pack) N45 Neodymium Bar Magnets, 1/4 x 1/2 x 3 Inches, #6 Countersunk Mounting Holes, Rare Earth

CMS Magnetics - (2-Pack) N45 Neodymium Bar Magnets, 1/4 x 1/2 x 3 Inches, #6 Countersunk Mounting Holes, Rare Earth

GRADE N45 RARE EARTH MAGNETS – Manufactured from sintered NdFeB for high magnetic strength and long-term stability under normal operating conditions. DEFINED POLE ORIENTATION – The countersunk face is South polarity, providing consistent magnetic orientation for applications where pole direction matters. COUNTERSUNK MOUNTING HOLES – Each magnet features two #6-size countersunk holes for flush mounting; fasteners are not included. PULL FORCE RATING – Up to 31 lbs of pull force under ideal laboratory conditions, measured with direct contact on clean, flat steel. DURABLE NICKEL PLATING – Triple-layer Nickel-Copper-Nickel (Ni-Cu-Ni) coating offers corrosion resistance for typical indoor use. These CMS Magnetics neodymium bar magnets are designed for strong, dependable holding performance in industrial, educational, and DIY applications. Made from Grade N45 sintered NdFeB, they provide high magnetic strength with excellent long-term stability. Each magnet measures 1/4 x 1/2 x 3 inches and includes two countersunk mounting holes sized for #6 fasteners, allowing flush installation into non-magnetic materials. Fasteners are not included. The magnets are axially magnetized, with the South pole located on the countersunk face, making polarity predictable for alignment-sensitive applications. Under ideal test conditions with direct contact on clean steel, each magnet provides up to 31 pounds of pull force. A Nickel-Copper-Nickel triple-layer coating enhances durability and corrosion resistance. Maximum recommended operating temperature is 176°F (80°C). When used within temperature limits and normal operating conditions, these neodymium magnets retain their magnetic properties indefinitely without measurable loss of strength. Common uses include workshops, fixtures, tooling, organization systems, educational projects, fabrication, and engineering builds.
