The Phillips or crosshead screw and screwdriver are named after Henry Phillips, who established the Phillips screw company in 1934. Phillips purchased the design from another engineer John Thompson, who had originally came up with the self centering design to speed production on assembly lines. General Motors adopted the Phillips head in 1936, consequently every garage in the United States needed them too, and the rest is history.
Narex wood line plus Phillips screwdrivers have strong beautifully ground tips. The tips are finished with a black high friction coating, that also serves as a substrate for the high quality chrome plating applied to the rest of the tool.
The handles of the Narex wood line plus range are made from beech wood, stained black, and are triangular in section giving optimal comfort and transmission of torque from the hand. The tang of the driver goes right through, so they can be lightly encouraged with a mallet or small hammer if necessary. The bolster is hexagonal so that a spanner can be used to provide additional leverage for intransigent screws.

To prevent damage to either the driver or the screw head, always use the correct size and shape of driver for the screw.
