JIS additional information.

Post by Ed Brock »



Just had to add this to the contest ad information.
JIS is commonly known as Japanese Industrial Standard as stated. It is however, used for much more the just a way to identify the philips screw look alike heads. It is also used in the world of hydraulics. In that world, the acronym identifies the thread/pitch and seat angle of the hydraulic fittings. JIS hydraulic fittings are different then their look alike JIC fitting.
Like the philips screw head that you can use a regular philips screw driver on, you can screw a JIS hydraulic fitting on to a JIC fitting most of the way, it just will not seal well. I have seen this issue several times when hydraulic JIS fittings began to be a common fitting.
There are also items JIS is used to identify.
While on this topic, I have some trivia. Does any know what the numbers on Japanese bolts mean? I have a number ID list if anyone needs it.

I will WORK AT figuring out how to send it to you. I need to "forward" it. Again, this computer thing is pushing my dinosaur brain.
It will take me some time to get that done. IF I can't figure it out I will update you and maybe you could help me do it.

it is a good chunk of info.

MikeB,
That is what I am referring to in my trivia question. Way to go, not many people have that information. Many, like myself, in shop class have been told those number refer to the bin the bolts on the assemble line are stored in. You get a paper telling you need X number of bolts, you go to that bin and get the required bolts and put your part of the process together.

Now remember this was years ago. I'm sure things have changed now.
