You can now attack just about every kind of box or enclosure that needs undoing with this Right Angle Phillips Head and Flat Head Screwdriver Kit. These right angled screwdrivers are ideal when you want something that's a cross between a regular driver and an allen wrench. Especially when there's a narrow spot you need to get into and you can't get a good angle to the screw head.

Each one can get into a spot with as little as 15mm / 0.6" of clearance. Note that, in particular, Phillips isn't designed for side torque so this is not for stuck bolts.

You get two 'wrenches' - each one with two heads on each end. Altogether you get a PH1, PH2, PH3 and a 1x6mm Flathead. The tips are magnetized so you won't have the unenvious experience of unscrewing a piece that then falls immediately onto the carpet.
