Measuring Hair Scissors

Korea, Japan, and China all use both inches and centimeters, but they mainly use the metric system. For example, the total length of the scissors are expressed in inches in all 3 countries. However, centimeters and millimeters are used for the parts and precision manufacturing processes. You can purchase a digital caliper with both units under $15 on ebay, and it would measure more accurately and easily when you have to replace the parts .

Most of the time, scissor factories use standard sized bolts, but it is not unusual to design a customized size bolt.

Let me show you some examples of measuring scissors or bolt. 0.01 mm is a very small difference, so you could have slight errors even when measuring the same part multiple times.  The following pictures show you how to measure the length and diameter.

The next pictures show you how to measure the square hole circled by the red line.  As you see in this photo, the actual size is 4.08mm.  The standard size is 4.0mm but the factory made it 0.08mm bigger.  The standard size for this square part of the bolt is 4.0mm, but its actual size is 3.95mm. In general, the square holes are made bigger and bolts are made smaller than its standard size. This is done so the parts fit together easily.

This time, let’s check the size of the circular hole inside of the blade.  The standard size is 5.0mm, but the actual size is 5.01mm.  The round part under the bolt head is 4.92mm but it is meant for a 5.0mm hole.
