Made from neodymium iron boron, it has a circular sinking hole that accepts a suitable countersunk screw, so you can fasten it securely rather than relying on magnetic attraction alone. The 15mm diameter is available in three thicknesses: 3mm, 4mm and 5mm. With a stated operating temperature of 80°C and a density of 7.5, it is intended for general craft, DIY and workshop use within those limits. Each pack contains one round magnet. Other sizes can be requested by consulting customer service.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"15mm round countersunk neodymium iron boron magnet with sinking hole, available in 3mm, 4mm and 5mm thickness\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/7041\/2025-11-17\/original-image\/2401280921240320800.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe magnet is built around a round neodymium iron boron disc with a central countersunk hole. This construction supports screw fixing for a flush result. The stated density of 7.5 and operating temperature of 80°C give clear parameters for use. The three thickness options let you match the magnet to the depth of your fixing point.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe magnet is made from neodymium iron boron, a magnetic material supplied here in a circular disc format. The countersunk hole is formed into the centre of the disc, allowing a screw to sit below the surface once fitted. This build is suited to holding tasks where the magnet needs to be mechanically fixed rather than simply placed. The silver tone appearance is typical of this material. No additional coatings or finishes are stated in the source information.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eThe round magnet has a 15mm diameter. Thickness options are 3mm, 4mm, 5mm, giving you a choice of depth for different fixing points. The 3mm version is the thinnest, the 5mm version is the thickest, and the 4mm sits between them. These are the only stated sizes, though the source notes that other sizes are available by consulting customer service. The countersunk hole is sized to accept a suitable screw for flush mounting, but no specific screw size is given in the source text.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"15mm round countersunk neodymium iron boron magnet with sinking hole, available in 3mm, 4mm and 5mm thickness\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/7041\/2025-11-17\/original-image\/9da86a9b-dce7-4fbd-a70a-bb146f518e49.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThis countersunk magnet is useful for craft projects, DIY fixes and workshop tasks where a strong but removable fixing point is needed. It can be screwed into place to hold small metal items, align components or secure lightweight objects. The 80°C operating temperature makes it suitable for environments that stay within that limit.\u003c\/p\u003e\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\u003cp\u003eIn workshop or professional settings, the magnet can be used for jigs, fixtures or temporary holding where a flush surface is important. The countersunk hole allows it to be screwed to a surface without the screw head protruding, which helps when the magnet needs to sit flat. The neodymium iron boron construction provides magnetic strength in a compact 15mm disc. The stated density of 7.5 and 80°C operating temperature should be observed for reliable use.\u003c\/p\u003e\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\u003cp\u003eAt home, this magnet can help with small repairs, craft projects or securing items where a screw-fixed magnetic point is more practical than adhesive. The 15mm diameter keeps it compact, and the three thickness options allow you to choose a depth that suits the task. It can be used to hold metal tools, fixings or decorative elements that are within its magnetic capability. The single magnet pack is suitable for trying one size before ordering more. Other sizes are available on request.\u003c\/p\u003e\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"15mm round countersunk neodymium iron boron magnet with sinking hole, available in 3mm, 4mm and 5mm thickness\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/7041\/2025-11-17\/original-image\/a393f579-cb16-4234-9616-65921a312a43.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe main benefit of this magnet is its countersunk hole, which enables screw fixing for a flush finish. The neodymium iron boron material provides magnetic holding in a small 15mm round format. With three thicknesses and a stated 80°C operating temperature, it covers a range of general fixing needs without unnecessary extras.\u003c\/p\u003e\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\u003cp\u003eAs a solid neodymium iron boron disc, this magnet has no moving parts and does not require special maintenance beyond keeping it clean and dry. It can be unscrewed and repositioned if needed, making it reusable for different projects. There are no stated care instructions beyond observing the 80°C operating limit and avoiding use outside its intended purpose. The density of 7.5 is a fixed material property.\u003c\/p\u003e\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\u003cp\u003eChoose this magnet if you need a round countersunk fixing point in a 15mm diameter, with the option of 3mm, 4mm or 5mm thickness. The neodymium iron boron construction and 80°C operating temperature are clearly stated. The single pack lets you test a size before committing to larger quantities. If you need a different diameter or thickness, consult customer service for available sizes. No performance claims beyond the stated data are made.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"15mm round countersunk neodymium iron boron magnet with sinking hole, available in 3mm, 4mm and 5mm thickness\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/7041\/2025-11-17\/original-image\/b498eeba-ea01-48e1-8a02-e3a1e3770812.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"15mm round countersunk neodymium iron boron magnet with sinking hole, available in 3mm, 4mm and 5mm thickness\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/7041\/2025-11-17\/original-image\/ccf6d743-a759-43a9-869e-07e82dc65e2c.webp\"\u003e\u003c\/div\u003e","brand":"qnaa1a-ru","offers":[{"title":"15x3 4mm","offer_id":59255746232651,"sku":"CJYD195877702BY","price":15.0,"currency_code":"USD","in_stock":true},{"title":"15x3 3mm","offer_id":59255746265419,"sku":"CJYD195877701AZ","price":15.0,"currency_code":"USD","in_stock":true},{"title":"15x3 5mm","offer_id":59255746298187,"sku":"CJYD195877703CX","price":15.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1035\/6686\/8811\/files\/b498eeba-ea01-48e1-8a02-e3a1e3770812.webp?v=1794507426","url":"https:\/\/doverelle.com\/products\/circular-sinking-hole-magnet-neodymium-iron-boron-round-disc-15mm-x-3mm-countersunk-hole-80-c-operating-temperature-for-craft-fixing-diy-projects-and-workshop-use-silver-tone","provider":"Doverelle.com","version":"1.0","type":"link"}
