kruiskopschroevendraaier

A kruiskopschroevendraaier, also known as a Phillips head screwdriver, is a type of screwdriver designed to drive screws with a cross-shaped recess in their head. This design was patented by Henry F. Phillips in the 1930s. The cruciform recess allows for greater torque to be applied to the screw compared to a slot-head screw, as the angled slots guide the screwdriver bit more effectively and reduce the likelihood of cam-out, where the screwdriver slips out of the screw head.

Kruiskopschroevendraaiers are commonly found in a wide range of sizes, indicated by a number system from 000 to 4, with smaller numbers corresponding to smaller screw heads. The tip of the screwdriver is precision-milled to match the recess in the screw head. While the Phillips head design is widespread, variations such as the Pozidriv exist, which have additional smaller slots between the main cross slots to further improve grip and reduce cam-out, especially in industrial applications. The distinct shape of the kruiskopschroevendraaier makes it a staple tool in households, workshops, and construction sites worldwide.
