Engineered for uncompromising strength and precision mounting, our 42mm M8 Countersunk Permanent NdFeB Pot
Magnet is the pinnacle of magnetic innovation for industrial and commercial applications. Combining the raw power of neodymium-iron-boron (NdFeB) with a robust pot design and a precisely crafted M8 countersunk hole, this magnet delivers exceptional holding force in a compact, user-friendly form.
At 42mm in diameter, this pot magnet offers a generous contact surface, ensuring maximum grip on ferrous materials. Its pot structure—encasing the high-grade NdFeB core in a protective steel shell—amplifies magnetic strength by focusing flux density, making it significantly more powerful than standard bare magnets of the same size. Whether securing heavy metal panels, anchoring machinery, or creating strong magnetic fixtures, its holding force stands up to rigorous daily use.
The integrated M8 countersunk hole is a feat of engineering precision, designed to accept M8 screws or bolts with a perfectly flush fit. This eliminates protrusions, ensuring a clean, low-profile installation that won’t interfere with surrounding components. The countersunk design also enhances stability, preventing wobble or slippage even under vibration or load—ideal for applications like automotive assemblies, conveyor systems, or industrial tooling.
Durability is built into every detail. The steel pot housing provides superior protection against impact, corrosion, and demagnetization, while the NdFeB core maintains its strength across a wide temperature range (up to 80°C for standard grades, with high-temperature variants available for extreme environments). A corrosion-resistant finish on the steel shell ensures longevity, making it suitable for both indoor and outdoor use, including workshops, construction sites, and outdoor signage.
