M5x8mm Philips Head Screw

Its M5x8mm Philllips Head Screw Phillips Head Bolt Colour The Phillips head screwdriver was created and patented by Henry Phillips in the 1930s and was originally used on the 1936 Cadillac. The great thing about it is that unlike the flat head screw (with a single ridge at its tip to slide into a screw with one slot), the Phillips screwdriver is self-centering. Its "X" design won't slip out of the X-slotted screw. Instead, it grips the screw firmly in the center, provided it's the suitable size for the screw.
