Cross-slotted head

More and more screws and bolts with a type of hybrid head are showing up on manufactured goods. It seems ( need research) this is especially the case with imported goods. These hybrid heads are of 2 types, and are similar in appearance:

1- the most common type in the US can best be described as an ordinary Phillips head, from which a slot has been cut out along the diameter of the head.

This slot is the same shape and size as the slot found on slotted screws. The original advantage seemed to be the extra convenience such a screw afforded the user, by allowing him to work with either a Philips or a slotted screwdriver, whichever is handy.r.While relatively common, these screws don't have a uniform name. Different companies have chosen their own name, such as plus/minus, ( more).

2- The second type is based on a pozidriv head, to which the slot has been added. This is more prevalent in Europe.
