• Select the Right Bit — Choose the appropriate S2 alloy steel bit from the 90-piece set based on the screw head type (Phillips, Torx, Slotted, Hex) and size. Ensure the bit fits snugly into the screw head to prevent stripping.
• Attach Bit and Use Extension (If Needed) — Insert the selected bit into the screwdriver handle or one of the extension bars (4in or 7in) for added reach. If working with small screws, consider using the magnetizer to attach the bit securely.
• Engage and Turn — Align the bit with the screw head and apply steady, axial pressure. Turn the ergonomic handle clockwise to tighten or counter-clockwise to loosen. The magnetic tip will help hold the screw in place.
