Neodymium Cylinder Magnets 1/4 x 1/4 Inch (6mm x 6mm) N48, 3.8 lbs – Strong Rare Earth Round Magnets for Cabinet Latches, 3D-Print Snap Fits & Wargaming (25 Pack)

A concealed magnetic closure starts with a single decision: which size fits the hole you can drill. These N48 neodymium cylinder magnets measure exactly 1/4 x 1/4 inch (6mm x 6mm) — the same 6mm as a standard drill bit — so they press into a bored pocket and sit flush without a gap or a routing jig. One magnet in the door, one in the frame; the flat pole faces attract directly and hold securely.Each cylinder is magnetized axially through its length, poles on the circular ends, so face-to-face attraction is instant and centered. The triple-layer Nickel-Copper-Nickel (NiCuNi) plating protects the rare earth core from moisture and minor abrasion, and leaves a smooth, polished surface that won't scratch wood, PLA, or foam on insertion. Maximum operating temperature is 80°C (176°F), standard for N-grade neodymium.Because equal diameter and height lock the cylinder in its bore without rotation, these magnets work equally well in 3D-printed snap-fit housings, routed wood cavities, and wargaming vehicle assemblies (turrets, hatches, swappable weapon arms). Drill a row of 6mm holes through the back of a wood block, press one cylinder into each, and face them flush — the result is a clean magnetic knife rack that holds kitchen knives through several millimetres of wood with no visible hardware. Pairs embedded flush in thermoplastic panels work for cosplay armor attachment where hardware needs to stay hidden.When two or more are needed, pairs spaced across the contact surface multiply holding strength reliably. The uniform coating and consistent dimensions across all 25 pieces mean every cylinder behaves the same — no weak magnets in the pack that undermine a multi-point closure.Warning: strong pinching hazard — handle carefully to avoid injury. If swallowed, magnets can bond across internal tissue and cause serious harm — keep away from children. Keep away from pacemakers and sensitive electronics. Not suitable for children under 14.

• N48 GRADE HOLDING POWER: High-grade N48 neodymium delivers up to 3.8 lbs of axial pull force — stronger than N35 or N42 at the same diameter, keeping closures and embedded assemblies firmly locked
• FITS STANDARD 1/4-INCH DRILLED HOLES: Drops into a 1/4-inch bore and seats flush with no gap — no routing jig, no visible hardware; one magnet per side creates a clean concealed closure
• WIDE RANGE OF APPLICATIONS: Hidden cabinet and box latches, DIY magnetic knife racks, snap-fit 3D-printed enclosures, wargame miniature magnetizing (vehicle turrets, hatches, weapon arms), craft closures
• SET OF 25, TRIPLE-LAYER COATED: 25 N48 cylinders with Nickel-Copper-Nickel plating for corrosion resistance and a smooth, scratch-free surface — consistent pull force and uniform dimensions throughout
• AXIAL MAGNETIZATION – POLES ON FLAT ENDS: Equal diameter and length lock the cylinder in its bore without rotation, keeping poles centered and face-to-face with the paired magnet across every piece in the pack
