The quick-change screwdriver is the ultimate multi-bit tool. Simply insert any standard bit into the socket or use as a 1/4 in nutdriver. To switch to a different bit, pull back the gold knurled collar, remove the bit and snap-in another. The tail-end features the E-Z Spin™ high torque rotating flip cap with built-in bit storage that holds up to 5 extra insert bits. This tool is as durable as it is useful. The driver blade has been coated in black oxide for superior corrosion-resistance and heat treated for optimum strength. Include this in your toolbox as the most versatile screwdriver you will ever need.
