I received the following in an email from a person only identified as Ross. I thank him. He sent me the following in reference to this post. concerning Philips and PoziDriv screws as used on Nakamichi Dragons and other Japanese equipment. I, too, have a set of Hozen drivers which I obtained from www.escience.ca
“You may also be encountering JIS (Japanese Industrial Standard, IIRC) crosspoint (not sure if “Phillips” is correct here, although people do say it) screws. These are a bit different than a standard Phillips, but don’t necessarily have telltale markings. One dot between two slots and near the center is the potential marking that I’m aware of. This is part of why I think you may be seeing JIS, not PoziDriv:

“I just encountered, AFAIK, my first PoziDriv’s, on a Maxtor HD.
“You might encounter these on Japanese-made RC vehicles (helicopters), cameras, print/copier machines, bike parts, (old, at least) Honda motorcycles, and probably a lot more things than people realize.
“PB Baumann (SwissTools) claims their Phillips tools are designed for DIN/ISO and JIS, but I don’t know if that’s truly possible. Hozan provides screwdrivers. Vessel (another Japanese company) makes some. Wiha, I heard, doesn’t know what JIS crosspoint is. Moody (RI company, specialize in “precision” drivers) makes some. Ames offers some. Jensen (part of Stanley?), I’ve heard does.
