How to use

Insert the 1/4" hex shank into a compatible screwdriver, bit holder, or quick-change chuck. Position the magnetic nut driver over the fastener so the magnet holds the screw or nut in place, then apply steady torque with a hand driver or powered driver as required. For assembly, ensure the bit is correctly seated on the nut head to avoid rounding. Replace the bit when wear or damage becomes visible.

Recommendations

Use with appropriately rated drivers and avoid exceeding recommended torque limits for the fasteners being used. Keep the bit clean and inspect regularly for wear. Store in a dry place to prevent corrosion despite the hardened steel construction.
