Durable Plastic Coating
These high quality magnets are protected by a tough layer of plastic. The finished dimensions, including the plastic coating, are 1 x 1/4 inch (Outer Diameter x Thickness). These magnets can be slammed together repeatedly without causing any damage. Furthermore, they are completely waterproof and weatherproof.

Installing Countersunk Magnets: Snug, Not Tight
Tighten each screw only until its head sits flush with the magnet, then stop. Neodymium is hard but brittle, so it can't flex like a steel washer. Once the screw head seats, every extra turn wedges it deeper into the countersink and can crack the magnet around the hole.
Use #8 flat-head screws. Avoid pan-head and round-head screws, which press on the thin edge of the hole.
Drive the screw by hand when you can. If you use a drill/driver, set the clutch to a low number, drive slowly, stop about one turn early and finish by hand. Don't use an impact driver or drill mode. Mount the magnet on a flat surface over a pilot hole, because a bump or glue drip underneath can crack it as you tighten.
