"Mom, can we have JIS? No, we have JIS at home."

One thing I noticed while trying to work on my 1997 KS3 was that some of the screws looked a little different. After some research, I learned that the screws that I thought were Phillips head were actually JIS or Japanese Industrial Standard screws. Below are some images I found on Pintrest regarding JIS screws.

JIS on the bottom of the above image. From the Wikipedia article on the JIS B 1012 screw head: "The JIS B 1012 was commonly found in Japanese made equipment, such as cameras and motorbikes. JIS fasteners superficially resemble a Phillips screw albeit one with narrower and more vertical slots. Compared to Phillips screws these differences give JIS fasteners less of a tendency to cam out. The bottom of the recess is flat, and the point of the driver has to be blunt. A Phillips screwdriver has the same 26.5 degree cone angle but because of the tapered slots will not seat fully, and will damage the screw if forced. A correctly sized JIS driver will engage at full depth into a Phillips or Pozidriv head screw slightly loosely, but without damage. JIS heads are often but not always identified by a single dot or an "X" to one side of the cross slot."

They come in several sizes:

• #000

• #00

• #0

• #1

• #2

• #3
