{"product_id":"neodymium-disc-magnets-4x2mm","title":"4mm x 2mm N42 Neodymium Disc Magnets","description":"\u003cp\u003eThe 4 x 2 mm N42 neodymium disc is the general-purpose choice for model components that need a firmer connection without an unusually deep recess. Its NiCuNi coating supports routine workshop handling, and axial magnetisation directs the holding force through the flat circular faces.\u003c\/p\u003e\n\u003cp\u003eThis size works particularly well for interchangeable equipment, removable vehicle sections, medium assemblies and lighter turrets. It offers a calculated, zero-gap pull reference of 340 g, with sideways shear estimated at approximately 50 g. The balance of width and depth makes it easier to place in many model parts than the deeper 4 mm option, while giving a much more positive fit than the thin panel magnet.\u003c\/p\u003e\n\u003cp\u003eDrill a 4 mm opening and cut the recess to 2.2 mm deep. For a purpose-designed 3D print, start with a 4.1 mm hole. Dry-fit the part before applying adhesive, mark the required polarity and secure the magnet with CA glue around the wall of the socket rather than leaving a thick layer beneath its face. Let the bond cure before checking the joint. Available pack sizes are 1, 10, 25, 50 and 100.\u003c\/p\u003e","brand":"Hobby Heaven","offers":[{"title":"1","offer_id":37686884368573,"sku":"MAG\/D4X2\/1","price":3.35,"currency_code":"CAD","in_stock":true},{"title":"10","offer_id":37686884401341,"sku":"MAG\/D4X2\/10","price":3.68,"currency_code":"CAD","in_stock":true},{"title":"25","offer_id":37686884434109,"sku":"MAG\/D4X2\/25","price":4.0,"currency_code":"CAD","in_stock":true},{"title":"50","offer_id":37686884466877,"sku":"MAG\/D4X2\/50","price":4.79,"currency_code":"CAD","in_stock":true},{"title":"100","offer_id":37686884499645,"sku":"MAG\/D4X2\/100","price":6.24,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0271\/9583\/4503\/files\/4x2mmHero1.jpg?v=1785936758","url":"https:\/\/hobbyheaven.org\/en-ca\/products\/neodymium-disc-magnets-4x2mm","provider":"Hobby Heaven","version":"1.0","type":"link"}
