Fishing Magnets with Countersunk Hole 4.72 inch 1500LBS Pulling Force

SUPER POWERFUL - This fishing magnet measures 4.72" (120 mm) in diameter, featuring a robust neodymium magnet base. It delivers 1500 LBS (680 KG) of pulling force under ideal conditions. HIGH QUALITY - The strong magnetic force is focused solely on the bottom; the other three sides are shielded by steel cups with negligible magnetic force, providing magnetic strength equivalent to 10 times that of a same-size magnet. The force is permanent and offers a long service life. Manufactured under ISO 9001 Quality Systems. BEST COATING - The Ni+Cu+Ni triple-layer coating ensures a shiny, rust-resistant surface.

The coated steel cup protects the magnet and helps prevent chipping or cracking. MULTIPLE USE - Unique design with a countersunk hole and eyebolt, ideal for retrieving various iron-containing nickel materials underwater and perfect for magnet fishing, lifting, hanging, and recovery tasks. Enjoy hunting for items like eyebolts, screws, hooks, fasteners, and more in your warehouse, garage, or yard. PERMANENT STRENGTH - Neodymium is a rare earth metal, well-suited for crafting permanent, powerful magnets. This fishing magnet retains its permanent magnetism and stays just as strong even decades later
