Neodymium Square Block Magnets 1/2 x 1/2 x 1/8 inch, N52 – 24 Pack

Product Description

Square neodymium block magnets are the first choice for builders who need a hidden closure without hinges, latches, or exposed hardware. A 1/2 x 1/2 x 1/8 inch block drops into a routed pocket in a cabinet door or presses into a square seat in a 3D-printed lid — no rotation, no gap, no alignment guesswork.Each piece delivers up to 9.1 lbs pull force through the flat face. Triple-layer nickel-copper-nickel plating seats flush in tight recesses without scratching. At roughly the footprint of a small fingernail and the thickness of two US nickels, these magnets recess cleanly in plywood, MDF, or printed PLA. The smooth nickel surface will not mar adjoining wood or scratch a painted PLA lid during open-close cycles.Unlike N35 magnets, the N52 grade holds reliably through 3mm of cabinet stock — one magnet pair replaces two weaker alternatives. Woodworkers building concealed chisel-box latches reach for this size because the square footprint covers the pocket edge-to-edge. Makers press these into CAD-designed cavities mid-print or glue them post-print; the block profile prevents the spin that round magnets allow in loose seats. For press-fit installs, uniform block dimensions hold without adhesive if the pocket is printed to tolerance.Will it hold a cabinet door? Yes — face-to-face through 3mm material at up to 9.1 lbs per pair. Square vs disc in a rectangular pocket? The block fills the cavity completely and cannot rotate. How many per lid? One pair for a small craft box; two pairs for wider panels. All 24 share identical dimensions, so every seat in a multi-point assembly closes with the same feel.Keep away from pacemakers and electronic devices. Swallowed magnets can attract through intestinal walls and cause serious injury — keep out of reach of children and seek immediate medical attention if ingested.
