The DIN 5260 specification, and subsequent revisions, incorporated the features of JIS screws into the screwdrivers. Differences between JIS and Phillips screws and screwdrivers are difficult to tell with the naked eye, but are easily noticed when using a screwdriver! Ces embouts et le support magnétique à tige de 1/4" sont parfaits pour une utilisation avec des visseuses sans fil dotées d'un mandrin rapide, des perceuses sans fil et des porte-embouts. X 75mm (2) +3 X 75mm (2) +3 X 75mm (2) Screwdriver Bits These Cross Point screwdrivers are designed to fit JIS (Japanese Industrial Standard) screws and Phillips screws Made in Japan according to JIS B4633 (Japanese Industrial Standard) Chrome Vanadium Steel with shot peening surface treatment 1/4" (6. But most other manufacturers don’t display JIS anywhere (Vera, Wiha, and even Japanese Hozan, to name a few I looked into in great detail).

B) shows how Phillips has a very slight curve (2) – not really visible to the naked eye (exaggerated in the drawing), but it makes the difference when force is applied, “helping” the screwdriver slip out (and in).Similar in look to a Phillips® screw, JIS screws are commonly found on Japanese equipment and are designed not to not allow the screwdriver to slip out of the screw head. JIS: JIS Ph1, JIS Ph2, JIS Ph3; Kreuzschlitz: Ph0, Ph1, Ph2 (x2), Ph3; Schlitz: 3, 4, 5, 6, 7 mm; Pozidrive: Pz1 (x2), Pz2 (x3), Pz3 (x2); Sechskant: 2, 2,5, 3, 4, 5, 6 mm; Sechsrund: T10, T15, T20, T25, T30, T40.

Based on that info, JIS has not been made obsolete, but most screwdriver manufacturers have stopped marking their tools using JIS and started marking their tools using ISO and DIN standards – i.The shafts of these screwdrivers are hexagonal so you can add some extra turning force with a small spanner as you push the handle down into the screw head.
