Attention:  I spoke to Alan and he suggested putting up the same post in several different spots to make sure the guys didn't miss it.....

If you are repairing a fishing reel made in Japan, you may need a JIS (Japanese Industrial Standard) based Screwdriver or JIS-based screwdriver bit. The JIS Cross-point, which looks like a Phillips®, is designed to fit perfectly into Japanese screws and will not “cam-out” like a Phillips® does.


A JIS and a Phillips® screw may look the same to the human eye, but they have completely different profiles. Phillips® drivers do not seat as deeply into JIS screw heads as the JIS tips do, and will typically damage JIS screws.

The Phillips® design was a solution for automobile mass-production lines, and was designed to “cam-out” after a certain torque was reached to prevent over-tightening of the screw. The self-centering design allowed operators to engage the tip of the driver into the cross-point screw head very quickly and easily, which was an advantage over the use of flat head screws.

Since 1916, VESSEL was Japan’s first volume manufacturer of screwdrivers and was a Key Member of the JIS (Japanese Industrial Standards) Association.  During that time, Japanese Engineers developed their own cross-point design similar to that of the Phillips®.  It was also self-centering and allowed the operator to engage the tip of the driver into the cross-point screw head quickly and easily.  However, the JIS design allowed torque and over-tightening to be controlled by the operator and not at the head of the screw.



A JIS screw can sometimes be identified by the presence of a small punch-mark of a dot or dimple on one side of the screw-head or an “X”, but this is not always true and some may have no marking at all.  In many cases, a JIS screwdriver or screwdriver bits can be used with Phillips® screws too.

Yep, I can remember posting about this numerous times, can we sticky something and put it to bed forever?

If you have Japanese reels, get J(apanese)IS drivers!    Undecided

Rick Hascup,  can you ship to us poor cousins in Australia at a reasonable postage rate?  Vessel are a bit scarce around here, I have a toolbox full but they are expensive to obtain from OS!

cheers
Steve

Getting back to Philips screw drivers, I grind the tip of my drivers, so they fit right into the screw, they don't slip so easy, cheers Don.

This is GREAT info - I never knew about JIS!  Since the only thing I like buying almost as much as fishing equipment is new tools, I believe I see a set in my future!  Couple of thoughts to add:
Tools do "wear out", even good ones.  You only have to slip off of a screw under pressure (Phillips, Standard, or otherwise) a few times and the "bit" of the tool will begin to become slightly compromised as well over time.  Combine that with folks tendencies to use their Standard screwdrivers as prying tools to open things like paint cans, beers, etc. it pays to periodically inspect the tip of the tool to make sure it's not the culprit in rounding out or gouging screw heads.
Another trick that I learned from my Dad, when you run into those screws that seem like they may be just a little over tight or maybe seized up, while there is a TON of great advice on the forum about various penetrating lubricants for the nasty stuck fasteners, one of the quick tricks that he taught me was to seat the tool into the fastener, and give it a light "tap" along it's axis.  Emphasis on the "light"; we're not looking to countersink, strip threads or bust heads.  Many times that little tap will "unfreeze" the fastener to where it will twist out with normal torque.

Also - if it's Asian assume it's JIS and use the appropriate bit/screwdriver - and sometimes hit it with heat (avoiding any plastic stuff)

I like playing with old guns, and so I make a bunch of my own drivers. My flat blade drivers do not slip, because I use or make hollow ground, parallel sided engagements that fit well. Lots of cross point bits are poorly manufactured and will not fit the fastener they were designed for well.

Concerning JIS / Phillips, the two can be readily differentiated after a bit. The JIS have corners with a much smaller radius. I bellieve the corners are supposed to be sharp, but that's difficult with mass production. There are actually Fearsons and a couple other cross tip designs. Plus the new fangled monstrosities that combine a #2 almost phillips with a #2 square drive. The only thing I like about those is that they are usually made of tougher material and you can go to town with an impact driver and not worry so much about twisting them off. Bottom line, know your fastener, use quality tools and get rid of / regrind a driver that shows any rear.

Ron are you talking about Posidrive heads on screws? Very popular throughout the world except, it seems, the US Undecided

Whenever I see a Phillips head screw, I reach for the nearest one and work the screw.  Sometimes it skips and dings the screw.  Is there a simple way to know which size Phillips head to use?  Dominick
