Heavy Duty Plastic Coated Neodymium Ring Magnet with Countersunk Hole

Durable Magnetic Solution for Demanding Environments

Stop worrying about shattered magnets and rust. This plastic-coated neodymium ring magnet is designed to withstand the toughest conditions while providing the extreme holding force only rare earth materials can offer. The specialized coating prevents the brittle magnetic core from cracking upon impact and shields it from moisture, making it a reliable choice for outdoor fixtures, marine use, and high-traffic workshops. Its countersunk design allows for quick, flush mounting on any flat surface, transforming how you approach joinery and organization.

Why You’ll Love This

• Corrosion-Proof Shield: The rugged plastic exterior protects the magnet from moisture and oxygen, preventing rust in humid environments.
• Superior Impact Protection: The outer coating absorbs energy, significantly reducing the risk of the neodymium core cracking or chipping during use.
• Easy Flush Mounting: The countersunk hole allows screws to sit flat, ensuring a clean, professional look for door latches and jigs.
• Compact & Powerful: Despite its small 16.5mm size, the rare earth core delivers industrial-strength magnetism for heavy-duty holding tasks.
• Multi-Purpose Utility: Ideal for mounting tools, joinery projects, metal retrieval, and magnetic sensor applications.
