3.5 Inch Rubber Coated Rare Earth Magnet with M8 Thread – Heavy Duty Mounting Magnet

Description

The 3.5 Inch Rubber Coated Rare Earth Magnet is a high-strength mounting solution engineered for demanding outdoor, automotive, marine, and industrial applications. Designed to deliver exceptional holding force while protecting painted, powder-coated, and metal surfaces, this magnet provides a secure, non-slip attachment point for custom brackets, antennas, Starlink mounts, lighting systems, tools, and more.

Its durable rubber coating prevents scratching and corrosion while increasing friction for improved grip, even in high-vibration environments. The integrated M8 threaded insert allows fast and reliable attachment to a wide range of hardware, making it extremely versatile for both temporary and semi-permanent installations.

**⚠️ Important: Magnetic strength may vary depending on material thickness, steel quality, surface condition, and temperature. Ensure the surface is clean for maximum holding power.
