Bit Holders
Set screws and nuts with bit holders and nutsetters. Most power tools can use bit holders and nut setters since they have universal quarter-inch hex shanks. A hex insert bit is used with a bit holder, and a magnetic nut driver can handle metal screws and other hex head fasteners with ease. A hex driver screw guide with a retracting sleeve can help stable long fasteners and is ideal for difficult-to-reach areas.
