Compared to Phillips screws these differences give JIS fasteners less of a tendency to cam out. The bottom of the recess is flat, and the point of the driver has to be blunt. A Phillips screwdriver has the same 26.5 degree cone angle but because of the tapered slots will not seat fully, and will damage the screw if forced.

Japanese Industrial Standard (JIS) cross-head screwdrivers are still another standard, often inaccurately called Japanese Phillips. Compatible screw heads are usually identifiable by a single depressed dot or an "X" to one side of the cross slot. This is a screw standard throughout the Asia market and Japanese imports.
The Phillips screwdriver design has a tendency to cam out during operation due to angled contact surfaces, which create an axial force pushing the driver out of the recess as torque is applied. Despite popular belief, [ 2 ] there is no clear evidence that this was a deliberate design feature.
The difference between a screw and a bolt is that the latter is designed to be tightened or released by torquing a nut. The screw head on one end has a slot or other feature that commonly requires a tool to transfer the twisting force. Common tools for driving screws include screwdrivers, wrenches, coins and hex keys.
The angle between the plane of contact between tool and fastener and the circumferentially directed force is much closer to 90° in a Torx type of head (lower) than in a conventional hex head (upper). (Exaggerated for illustrational purposes) By design, Torx head screws resist cam out better than Phillips head or slot head screws. [1]
