When a cross-head screw is not Philips, and you might need a JIS screwdriver
Posted by jpluimers on 2021/12/06
A while ago, when messing with some Asian electronics, I found that the cross-head screws in it do not fit Philips screwdrivers well.
The cause is the use of JIS (Japanese Industry Standard) cross-head screws in Japan and some other Asian regions.
JIS screws can also been found in other Asian mechanical stuff like motor-cycles and cars.
Here are some links about JIS screws and screwdrivers.
