Tool kits Phillips (PH) bits

PH

— bits with a classic cross-shaped tip that does not have additional elements (unlike PZ). One of the features of such tips is the tendency to jump out of the slot with a critical increase in load. In a sense, this is an advantage: it reduces the risk of overtightening the fasteners, as well as damaging the slot and nozzle due to too high a load. On the other hand, for work at high forces, this type of spline is relatively poorly suited.

It should be noted that PH cross bits can also be used with PZ slots, but not vice versa.
