{"product_id":"neodymium-disc-magnets-4x1mm","title":"4mm x 1mm N42 Neodymium Disc Magnets","description":"\u003cp\u003eThese 4 x 1 mm N42 neodymium discs provide a broad contact face without asking for much depth. They are axially magnetised and finished with a NiCuNi coating, making them well suited to flat model components where a narrow, deep hole would be impractical.\u003c\/p\u003e\n\u003cp\u003eThis is the panel and hatch option in the range. Use it for removable covers, access doors, thin armour plates, cowlings and similar parts that offer surface area but very little material behind the joint. The calculated, zero-gap pull reference is 160 g, while sideways shear is estimated at approximately 20 g. Its value comes from spreading the magnetic contact across a 4 mm face while keeping the required recess shallow.\u003c\/p\u003e\n\u003cp\u003eUse a 4 mm drill and make the socket 1.2 mm deep, taking care not to break through a thin wall. A 4.1 mm hole is the starting point for a 3D-printed part. Because the disc is only 1 mm thick, press it level while the CA glue takes and make sure no paint or excess adhesive sits between the mating faces. Select packs of 1, 10, 25, 50 or 100 magnets.\u003c\/p\u003e","brand":"Hobby Heaven","offers":[{"title":"1","offer_id":37686876045501,"sku":"MAG\/D4X1\/1","price":2.09,"currency_code":"GBP","in_stock":true},{"title":"10","offer_id":37686876078269,"sku":"MAG\/D4X1\/10","price":2.39,"currency_code":"GBP","in_stock":true},{"title":"25","offer_id":37686876111037,"sku":"MAG\/D4X1\/25","price":2.99,"currency_code":"GBP","in_stock":true},{"title":"50","offer_id":37686876143805,"sku":"MAG\/D4X1\/50","price":3.79,"currency_code":"GBP","in_stock":true},{"title":"100","offer_id":37686876176573,"sku":"MAG\/D4X1\/100","price":5.59,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0271\/9583\/4503\/files\/4x1mmHero1.jpg?v=1785936642","url":"https:\/\/hobbyheaven.org\/products\/neodymium-disc-magnets-4x1mm","provider":"Hobby Heaven","version":"1.0","type":"link"}
