OK, I thought I had a pretty good understanding of simple tools.
So much so, that the school teacher that married my niece in 1969,
I have ALWAYS teased him that he did not know which end of a screwdriver fit in his hand!!
WELL, Now, I come to find out, that I fit in that EXACT category,,
China stuff is relatively new, compared to what I have fixed since the 1950's,,
In between USA made, and China made,, there was Japan made stuff,, motorcycles, machining tools, drill presses, anything,,
Well I have always owned some sort of Phillips head screwdriver,
and, I have used basically the same Craftsman set of screwdrivers since the 1950's, replacing some when they were lost, with the identical tool.
NOW, I come to find out that Japan made stuff has a screw that LOOKS like a Phillips head, but, the typical Phillips head screwdriver will destroy the Japan made screw.
There is a special tool called a JIC driver, just for Japan made stuff,, it is not a Phillips head,
WHY DIDN'T ANYONE EVER tell me!!??
This video has poor audio, but it is only one minute, so it does not take much of your time,,
(You would think a company as big as Chapman would know better audio is needed in this day and age,,)
"Does your Phillips driver feel like it doesn't quite fit that screw? Chances are that's because it's not a Phillips screw, it's a JIS screw.
JIS, or Japanese Industry Standard screws are just different enough in shape that Phillips drivers will not fit well and slip/strip them. The difference is in the leading angle of the point of the driver. Phillips bits have a larger angle and therefore don't bottom out in the JIS screws, causing slippage. "
So, have you ever found out that you knew less about a tool, than you THOUGHT that you did??
