is based on lab tests with flat, bare steel. Actual holding force may be lower if the surface is curved, coated, dirty, or the screw doesn’t allow flush contact. For best results, ensure full contact with clean ferromagnetic surfaces and use compatible flat head screws.\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eAre there safety precautions I should follow when using this magnet?\u003c\/strong\u003e\u003cbr\u003eYes. Due to its extreme strength, this magnet can snap onto metal or other magnets quickly, risking pinched fingers or chipping. Always handle with care, keep away from electronics and pacemakers, and avoid colliding the magnet with hard surfaces.\u003c\/span\u003e\u003c\/p\u003e","brand":"Applied Magnets","offers":[{"title":"Default Title","offer_id":52545955168570,"sku":"ND057-2","price":6.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0978\/9495\/7370\/files\/ND057-1_magnet_2.jpg?v=1771447530","url":"https:\/\/supermagnetstore.com\/products\/very-strong-n52-neodymium-magnets-1-in-x-1-4-in-w-dual-sided-countersunk-hole-disc","provider":"Super Magnet Store","version":"1.0","type":"link"}
