The KAILIWEI 045 Hollow Magnetic Screwdriver is a specialized hand tool crafted for the maintenance of smartphones, tablets, laptops, and other精密 electronic devices. The defining characteristic of the "045" model is its hollow shaft design, which allows it to fit over long standoffs or guide pins that are common on stacked printed circuit boards (PCBs), such as those found in iPhones and MacBooks.

Key Features

• Hollow Shaft Design: The core feature of this screwdriver is the hollowed-out barrel. This allows it to accommodate long screw posts or alignment pins found in multi-layer motherboards, enabling the removal of deeply recessed screws that standard solid shafts cannot reach.
• Magnetic Tip: The tip is engineered with strong magnetic adsorption, specifically calibrated to securely hold and retrieve tiny micro-screws (like Phillips or Pentalobe) without dropping them into the device chassis.
• Durable Construction: Constructed from high-hardness alloy steel (typically S2 or Chrome Vanadium), ensuring the tip resists wear and "cam-out" (slipping) under torque.
• Ergonomic Handle: Features a knurled or anti-slip texture to provide excellent grip, often paired with a smooth rotating cap for precise fingertip control during delicate disassembly.
