Measuring 18mm outer diameter with a 7mm height, this neodymium ring magnet features a precision countersunk centre hole (10.4mm countersink with 5.5mm inner diameter), making it ideal for flush screw mounting in cabinetry, fixtures, displays, machinery, and industrial assemblies. This magnet suits an M5 countersunk screw. \u003cbr\u003e\u003cbr\u003eThis magnet is identified by product code 23016.\u003c\/p\u003e\n\u003cp data-start=\"435\" data-end=\"832\"\u003eManufactured from premium N30SH-grade neodymium, this magnet is designed to withstand operating temperatures up to 150°C, making it suitable for environments where standard neodymium magnets may lose strength due to heat exposure. The magnet is axially magnetised, with the north polarity located on the countersunk face, allowing for reliable directional installation in specialised applications.\u003c\/p\u003e\n\u003cp data-start=\"834\" data-end=\"1185\"\u003eFinished with a durable triple-layer NiCuNi (Nickel-Copper-Nickel) coating, this countersunk ring magnet offers excellent corrosion resistance along with a polished metallic appearance. Despite its compact size, it delivers an impressive pull force of approximately 13.2kg under ideal conditions when in direct contact with a thick mild steel surface.\u003c\/p\u003e\n\u003cp data-start=\"1187\" data-end=\"1270\"\u003eCommon applications for this high-temperature countersunk neodymium magnet include:\u003c\/p\u003e\n\u003cp\u003eFlush-mounted magnetic fastening systems.\u003c\/p\u003e\n\u003cp\u003eIndustrial and engineering projects.\u003c\/p\u003e\n\u003cp\u003eAutomotive and high-temperature environments.\u003c\/p\u003e\n\u003cp\u003eWorkshop jigs and fixtures.\u003c\/p\u003e\n\u003cp\u003eSignage and display mounting.\u003c\/p\u003e\n\u003cp\u003eCabinet closures and hidden fixings.\u003c\/p\u003e\n\u003cp\u003eRobotics, automation, and manufacturing systems.\u003c\/p\u003e\n\u003cp data-start=\"1563\" data-end=\"1812\" data-is-last-node=\"\" data-is-only-node=\"\"\u003ePlease note: Pull force ratings are based on ideal conditions and may vary depending on steel thickness, surface finish, mounting orientation, and air gaps.
