- Operating Temperature: Max working temperature of 176°F (80°C)
- Tolerances: Precision ground to +/- 0.002" (+/- 0.05 mm)
Common Applications:
Engineered for heavy-duty mechanical mounting and reversible installations, this double-sided countersunk disc magnet is ideal for:
- Heavy cabinet latches, magnetic door stops, and enclosure locks
- Custom woodworking jigs, shop holding fixtures, and tool mounts
- Industrial equipment mounting, signs, and retail displays
- DIY hidden magnetic latches requiring flush-mount screw fastening
⚠️ CRITICAL SAFETY WARNINGS:
- PACEMAKER & MEDICAL DEVICE SAFETY: Strong magnetic fields can interfere with pacemakers, ICDs (Implantable Cardioverter Defibrillators), and other electronic medical implants. 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 all children.
- CHOKING & SWALLOWING HAZARD: If swallowed, powerful neodymium magnets can snap together across intestinal walls, causing severe injury or death. Seek immediate emergency medical care if ingested.
- PINCH HAZARD: Generating 46 lbs of pull force, this magnet can snap unexpectedly to steel or other magnets, 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
