Holy hell I didn’t know why all my Japanese bikes bolts get stripped. And now I know, the rest of the story. Thanks. I didn’t know about JIS at all. Going shopping tomorrow
I had to replace all the screws on my last Honda motorcycle with Allen screws back in the late 60s. Nobody realised that the original screws were JIS and Phillips screwdrivers just chewed all the screw heads. Recently I bought a set of JIS screwdrivers. Amazing difference.
Pozidriv screws look completely different from Phillips/JIS, they have the little fins in between the main arms of the cross. You can get away with using a Phillips driver in a Pozi screw, but not the other way round. Pozi screws are still the most common in the UK for woodwork and general construction purposes, though less so on machinery.
If you’re looking for Pozidriv screws, go find a British car made in the sixties or later. MGBs are loaded with them, including the screws for the door hinges, which are huge, perhaps #4 or #5. As a British car owner, I was quite familiar with Pozidriv, but didn’t know about JIS. This now explains why I had stripped so many screws over the years on various bits of electronic equipment!
I find Phillips and Posidrive to work fine most of the time on each other's screws. Both have trouble with J.I.S. screws. However, my J.I.S. Screwdriver seems to handle posidrive and Philips crews with rare problems.
Great video. How is it that I've been using screws for decades and not know this? But does the camera not have a manual focus or focus lock? 8:24 onwards is more useful, and less nauseating.
Few years ago i learned of these different types - NEVER Knew . . . - but Screws did. Thanks. Still find myself using wrong one - not on purpose. Long Gone is just Philips or straight.
Good analysis of the cruciform screws . Fancy 20 different types. The problem is the Patent System .And if JIS are supposed to be so good , why do Japanese have a special unfriendly word for Foreigners after we buy so much of their stuff ?
In my experience JIS screwdrivers work fine in Phillips, but Phillips screwdrivers lead to rounding on Jis screws. If you are working on Japanese stuff you need a JIS set. In fact, I feel like the JIS works better in Philips than Phillips screwdrivers do. I think it will be clearer if you stop calling JIS or Frearson forms of Phillips like “European Phillips.” That leads to confusion.
Could you tell me a definitive way to identify the difference between JIS and philips since they don’t always have the dot on them. Also, LONG LIVE THE TORX! Long live the torx!
@@amezcuaist oh, yeah. my I FIX IT tool kit has a jis driver set in it an i noticed that. i was more referring to the screws themselves. how do I identify them to make sure I use the right driver?
Problem: 20 competing cruciform screw and driver systems. Solution: Create a new universal standard cruciform screw and driver system. Result: 21 competing cruciform screw and driver systems.
Posidriv screws don't just have marks. There are actually cuts which allow the slots to distort and grip the screwdriver. And it was patented by GKN in the UK, not Phillips.
Pozidrive are very common in UK. If you go and buy some self tappers or woodscrews (or small machine screws I suspect) they will be pozidrive unless you seek something else. e.g. - quite a big national chain www.toolstation.com/screws-fixings/screws/wood-screws/c852 494 screw types catalogued 233 pozidrive 77 pozisquare - I have never heard of these ?? 65 Torx
