【Strong Magnetic】 Strong magnetic screw ring securely holds screws on the bit, reducing the risk of falling or slipping. Works especially well in narrow spaces or at awkward angles. The magnetic screw ring is designed for 1/4 inch (6.35 mm) hex screwdriver bits, ensuring a snug fit for standard drill and screwdriver bits. 【Usage Steps】 Select the appropriate 1/4 inch (6.35 mm) hex bit and insert it into your drill or screwdriver chuck. Place the magnetic screw ring on the front end of the bit, as close to the tip as possible—this is crucial for optimal magnetic effect. Place the screw onto the tip—the magnet will automatically attract and hold it in place. Start the drill or screwdriver to drill or tighten the screw.️ Tip: For best performance, always position the magnetic screw ring at the front end of the bit near the tip. Placing it farther back reduces magnetic hold and may cause screws to slip. 【Multifunctional Use】 Screwdriver bit and magnetic screw ring combination can provide excellent performance in home improvement, engineering construction, automobile repair and electronic product assembly. They are suitable for the installation and removal of various screws, especially in hard-to-reach places, ensuring efficient and precise operation.
