Featuring built-in neodymium iron boron permanent magnets (magnetic flux density ≥800Gs), these sockets securely hold M2-M12 hex bolts/screws, with adsorption forces ranging from 1-5kg (increasing with size). This is ideal for preventing drops in overhead work, inverted installations, or tight spaces, enhancing efficiency by over 40%.

The hexagonal inner bore uses laser-milled tooth patterns, achieving over 95% contact fit with bolt heads and reducing torque loss to less than 2%. When paired with ratchet wrenches or power tools, they ensure stable power transmission even at 50N·m torque (e.g., heavy-duty bolts in furniture assembly), preventing slippage or edge wear on screws. This makes them suitable for precision applications like electronics and automotive interiors.

Available in 2mm-12mm metric/imperial sizes, they come in short (3cm), standard (7cm), and extended (15cm) lengths. Short models excel in micro-tasks like eyeglass screws or watch movements, while extended versions with flexible hose adapters reach deep into pipes or equipment gaps (e.g., air conditioning compressors). Select models support 1/4" and 3/8" square drive interfaces for compatibility with mainstream tools.

The magnet surface is coated with scratch-resistant rubber to protect bolt plating, and a quick demagnetization button at the tail eliminates magnetism for easy screw removal. Sets include magnetic storage panels for organized, size-specific placement to prevent loss.

Aluminum alloy models feature anodized surfaces, while plastic variants use anti-aging nylon 66, both resisting oil, moisture, and weak acids/alkalis (e.g., bathroom repairs) with a lifespan exceeding 5 years. Magnetic decay tests show only a 5% loss in adsorption force after 100,000 uses, far outperforming standard magnetic tools.
