Nut driver for M4 nuts. These must be used with a handle! The socket end has a magnet to hold on to the nut, but it is not very deep. If the screw will extend past the end of the fastener, a deeper nut driver or wrench will be required.

M4 nuts are 7mm from flat-to-flat. M4 fasteners are standard with goBILDA hardware.

These are sold individually. Handle sold separately.
