That title got my attention!!!

Apparently almost every nationality has a screw. Just another reason to travel.

Holy moly. That's a lot of screw types. Jackasses should narrow it down to like 2 or 3. Cross-slots anyway.

Step 10: JIS - Japanese Industrial Standard














Often improperly referred to as Japanese Phillips. Commonly found in Japanese equipment. JIS looks much like a Phillips screw (and even more similar to Frearson), but is designed not to cam out and will, therefore, be damaged by a Phillips screwdriver if it is too tight. Heads are usually identifiable by a single raised dot to one side of the cross slot. JIS B 1012:1985 screw standard is throughout the Asia market and Japanese imports. The driver has a 57 degree point with a flat tip, parallel wings.

Advantages and Disadvantages of JIS

Most people and companies outside of Japan have absolutely no idea what they are. With the similarity in appearance to the Frearson and the Phillips the screws are often damaged in removing and installing with the wrong tools. JIS tends not to camout like Philips. The JIS driver can be used on Phillips quite easily but not reciprically. Drivers are not easily available in North America, try your local RC Airplane hobby shop. Most RC Helicopters use JIS screws to mount the propeller. JIS-spec cross-head screws are generally marked with a single raised dot or an "X". JIS always fit Phillip fasteners, but because of slight design differences, Phillips drivers may not fit JIS fasteners. (unless the tip is ground down a bit).

Fascinating.

Just remember that your FJR uses the JIS standard for its cross-headed screws, and Yamaha kindly provides a suitable screwdriver in the tool-kit.

Yup, I have several JIS screwdrivers, and you can feel the difference when you use them.

2 is enough. Plus and minus.

Problem solved.

Jeezus, there's more there then I thought. I know I've had to spend some money through the years collecting the right drivers for fasteners I've come across. Like that "security screw" they used on the hinges of the FJR's hard cases...(why the hell do you need a security screw on a hinge that is on the inside of a locking case??)

Back in the late 70's, everyone was replacing the cross head bolts on their Japanese bikes with Allen heads. I remember buying a set of Allen heads (about $30 back then) that replaced ALL the bolts on my RD 400, along with a Allen driver with a 3/8" drive base. Was really nice however when working on the bike.

So now I have security head, Torx, Allen, JIS, and even square drive bits, that for the most part, I very rarely use. Oddly missing is a triangular drive on the list, but I'm sure some *** will come out with one...

Pro tip- since we all know that security screw on the saddlebags wasn't loctited in by the dealer, so it's very easy to remove with needle nose pliers or vise grips.
I pulled mine off that way, and it was surprising and a little scary how easily they came off.

That's screwed up, John.

That's what she said.

 

[eflyguy]

I like to keep the provided driver handy when working on the bike. If a fastener is a bit sticky, it's good to use the designed driver than to mangle it with the incorrect tool...

I bought a small set of JIS drivers a few years ago, but have never needed them.

That certainly was the opinion of most crewmen on my submarine.
