Using the Makita A-97128 ImpactX magnetic nut driver is a breeze. First, select the appropriate driver bit from the pack of 10. The magnetic feature allows you to easily pick up hex fasteners. Simply place the bit in your high-torque impact driver and start driving screws. The lobular design and flat edges at the hex opening ensure a proper fit and prevent fasteners from rounding. When using, make sure your impact driver is set to the right torque for the job. Don't use it with extremely high torque settings that could damage the bit. For maintenance, keep the bits clean after each use. You can wipe them with a dry cloth. Store them in a dry place to prevent rust. With proper use and care, these nut drivers will serve you well for a long time.
