Neodymium Cylinder Magnets 6x12mm (1/4x1/2 inch) N48 – 20 Pack | Rare Earth Rod Magnet for Whiteboard, Craft Projects, Woodworking, Tool Organization,($23.49Value)

Description

N48 GRADE, 3.9 LB PULL FORCE – Each 6x12mm (1/4 x 1/2 in) rod magnet delivers a verified 3.9 lb (1.7 kg) pull, giving you reliable holding power for mounting, organizing, and securing tasks. TRIPLE-LAYER NiCuNi COATING – Nickel-copper-nickel plating protects against rust and corrosion, keeps the surface smooth and scratch-resistant, and ensures long-term performance even in humid garages or workshops. VERSATILE APPLICATIONS – Elongated cylindrical shape works as a recessed magnetic fastener in pre-drilled holes or seats firmly in tight spaces; use for whiteboard and fridge mounting, map pinning, tool organization, craft projects, and model building. IDEAL FOR WORKSHOPS, OFFICES, AND CLASSROOMS – Elongated shape provides a stable hold in fixture slots, cabinet insets, and alignment channels; suited for lab setups, school science demonstrations, and small-scale fabrication work. 20 MAGNETS PER PACK – Quantity covers multiple simultaneous projects; uniform dimensions (6mm dia x 12mm length) ensure consistent performance across every piece in the set. These N48 neodymium cylinder magnets measure 6mm in diameter and 12mm in length (approximately 1/4 x 1/2 inch) and deliver a pull force of 3.9 lb (2.86 kg) per magnet. The elongated rod shape creates a longer magnetic contact surface compared to a standard disc, making it easier to align components, seat magnets in drilled channels, and achieve a stable hold in both shallow and deep-mount applications.
The triple-layer Nickel-Copper-Nickel (NiCuNi) coating provides strong resistance to corrosion and oxidation, a smooth finish that resists scratching, and added structural protection against chipping. Magnetization runs axially along the length of the cylinder, concentrating field strength at both flat ends for maximum grip on ferromagnetic surfaces.
Common uses include fridge and whiteboard mounting, map and poster pinning, tool and hardware organization in garages and workshops, jewelry and accessories storage, scrapbooking, miniature modeling, and school or lab science setups. Their compact diameter allows them to fit inside pre-drilled holes in woodworking, cabinet-making, and small-part fabrication projects where a flush or recessed magnetic fastener is needed.
Safety and handling: These are strong magnets. Two or more magnets can snap together forcefully and pinch skin. Keep away from pacemakers, implantable defibrillators, and other magnetically sensitive medical or electronic devices. Not suitable for children under 14. Store separately from credit cards, hard drives, and similar media. Handle with care to avoid personal injury or damage to surrounding items.
Each pack contains 20 magnets with consistent dimensions and uniform magnetic performance. Suitable for professional, hobbyist, and educational use across a wide range of environments including kitchens, offices, classrooms, labs, and fabrication shops.
