Product Description
Engineered specifically for heavy-duty structural mounting with larger mechanical fasteners, this N45 Neodymium Disc Magnet measures 1" Diameter x 1/2" Thickness (1.00" x 0.50" / 25.4 mm x 12.7 mm) and provides 45 lbs of surface holding force. It features a precision-machined double-sided 82° countersunk hole tailored for #12 flat-head screws, allowing completely reversible, flush-mount installation on both sides without fastener heads interfering with contact points.
Key Features & Specifications:
- Magnetic Grade: Grade N45 Sintered NdFeB (13,500 Gauss / 1.35 Tesla Residual Flux Density $B_r$)
- Dimensions: 1.00" Outer Diameter x 0.50" Thickness (25.4 mm OD x 12.7 mm Thk)
- Fastener Compatibility: Dual-sided #12 countersunk hole (~0.435" top outer diameter taper, accepting #12 flat-head wood and machine screws)
- Reversible Dual Countersink: Fully symmetric 82° bevel on top and bottom faces for dual-directional screw mounting
- Pull Force: 45 lbs (20.4 kg) direct pull strength against flat, solid steel plates
- Magnetization Axis: Axially magnetized through the 1/2" thickness (Poles on circular flat faces)
- Plating & Coating: Durable Triple-Layer Ni+Cu+Ni (Nickel-Copper-Nickel) protective barrier
- Thermal Limit: Maximum operating temperature up to 176°F (80°C)
Key Applications & Hardware Integration:
Compared to smaller #10 fastener magnets, this #12 countersunk disc magnet accommodates heavier-gauge screws required for high-load mechanical connections:
- Heavy-duty cabinet door latches, gate catches, and industrial enclosure closures
- High-torque woodworking fixtures, CNC holding jigs, and shop tool retainers
- Reversible structural framing brackets and concealed magnetic mounting plates
- Equipment mounting requiring robust #12 wood screws, sheet metal screws, or machine bolts
⚠️ CRITICAL SAFETY WARNINGS:
- PACEMAKER & MEDICAL DEVICE SAFETY: Strong magnetic fields can interfere with pacemakers, ICDs (Implantable Cardioverter Defibrillators), and electronic medical devices. Maintain a safe distance (at least 12 inches / 30 cm).
- NOT A TOY: This product is intended for commercial, industrial, and craftsmanship applications. It is NOT a toy and must be kept away from children.
- CHOKING & SWALLOWING HAZARD: If swallowed, powerful neodymium magnets can stick together across intestinal walls, causing severe injury or death. Seek immediate medical attention if ingested.
- PINCH HAZARD: Producing 45 lbs of force, this magnet can snap unexpectedly to steel objects, causing severe pinching, blood blisters, or skin lacerations. Handle with extreme care.
Warranty
This magnet includes a 10-year warranty for its magnetic strength, provided it is used under normal conditions. Usage in environments with elevated temperatures, significant vibration, or intense opposing magnetic fields will render this warranty null and void. It is also not suitable for use outdoors or in areas with high humidity or salt content, unless additional protective insulation measures are implemented.Product Videos
