ARES27006-3-Piece 10mm Magnetic Impact Nut Driver Bit Set - 6-Inch Length - Impact Grade Nut Setters with Industrial Strength Magnets

Hasn't failed me yet!!!

Description clearly mentions 3-Piece 9/16" Magnetic Impact nut driver. Received one 36mm monster, and came in 3 weeks late. Not cool

I install garage doors and in one day of use, the magnets fell out of all of them.

I install garage doors so I constantly use a 7/16 magnetic for the door screws. This has a fairly strong magnet, my old one was one from denco. It lasted a long time until recently the magnet broke slightly and lost a lot of the hold. Then the magnet came out. So time for a new one. I got 3 for the price of one with these. So if all 3 can make it a while I’d say money well spent. Shipping was quick. Will def buy more if they hold up

Built well, however the magnet had to be set deeper to be usable. All bit extension magnets were not set deep enough which caused the bits to spin due to minimum socket contact surface area. Used a centerpunch and set them lower. The adjustment made them work excellently.
