N52 Neodymium Countersunk Disc Magnets 3/8x1/16 inch (10x1.5mm) #4 Screw Hole – Strong Mounting Magnets for Crafts, Doors & Cabinets, Crafts & Workshop, 30 Matched N/S Pairs (60 Pack)

These N52 neodymium disc magnets are built for permanent screw-mount installation in workshops, kitchens, garages, classrooms, and craft rooms. Each magnet measures 3/8 inch in diameter and 1/16 inch thick, with a precision-machined #4 countersunk hole - ready to seat flush against any flat surface using a standard wood or machine screw. The 60-piece pack includes 30 north-south matched pairs, making these a practical choice for systems where consistent polarity matters.At N52 grade, each magnet delivers up to 2.4 lb of pull force - significantly more than the N35 or N42 discs typically found in bulk assortment packs. Triple-layer nickel-copper-nickel plating protects against rust, oil, humidity, and surface wear, making these suitable for long-term use in garage or kitchen environments where exposed magnets degrade quickly.In a workshop, these mount cleanly under shelves or inside cabinet doors to hold drill bits, hex keys, or small metal parts. The slim 1/16" profile sits flush in routed recesses and handles sawdust and cutting oil without corrosion. For kitchen use, they work well in under-cabinet spice jar rails or custom door closures where a magnet and strike plate replace traditional hardware. In classroom or lab settings, matched polarity pairs are used for repeatable field-mapping experiments and assembly demonstrations.The countersunk design solves a common problem with flat disc magnets: they hold to surfaces but do not attach to them. A single #4 screw locks each magnet permanently in place without adhesive, brackets, or epoxy. This makes repositioning straightforward and eliminates the adhesive failures common in high-humidity or high-vibration environments.Keep away from pacemakers and implanted medical devices. Strong pinching hazard - handle with care when working with multiple magnets. Not suitable for children under 14.

• PRECISE SPECS AND STRONG HOLD – Each disc is 3/8 x 1/16 inch (10x1.5mm) with a #4 countersunk hole. N52 grade delivers up to 2.4 lb pull force per magnet; triple nickel-copper-nickel plating ensures corrosion resistance.
• SCREW-MOUNT INSTALLATION – Countersunk profile allows flush, permanent attachment to wood, metal, or plastic with a #4 screw. Eliminates adhesive magnets that fail over time or under sustained load.
• WORKSHOP AND GARAGE ORGANIZATION – Build magnetic drill bit holders, sanding belt racks, pegboard mounts, or removable jigs. Slim 1/16" profile fits tight recesses and resists oil and sawdust.
• KITCHEN, OFFICE, AND DISPLAY USE – Install spice jar rails under cabinets, create modular whiteboard or door-closure systems, or mount display panels. NiCuNi plating resists humidity and daily handling.
• N52 GRADE PERFORMANCE – N52 neodymium outperforms N35/N42 discs of identical size; 60-piece pack includes 30 north-south matched pairs for polarity-sensitive assemblies and STEM projects.
