Product Description

These 3/8" x 1/4" N40SH neodymium disc magnets are built for situations where heat is part of the job. Unlike standard magnets that start to weaken when temperatures climb, these are designed to keep their hold steady even in environments that run hot, up to around 300°F (150°C).

The thicker 1/4" profile gives them a solid, stable feel in use, while the 3/8" diameter helps spread the contact area for a more secure grip. That combination makes them easier to trust in real setups where vibration, heat, or repeated use can slowly loosen weaker options over time.

They’re often used in motors, sensors, mechanical assemblies, and equipment where things naturally warm up during operation. They also fit well in workshop builds, automotive projects, or any setup where parts need to stay in place even when conditions aren’t ideal.

A simple nickel coating helps protect the surface from wear and corrosion, so they hold up over time without needing special care. Installation is straightforward, and once they’re in place, they’re meant to stay there and keep doing their job without much attention.

A practical high-temperature magnet for when regular neodymium isn’t enough.
