1. To prevent over-tightening

The spring nut, which is used extensively on the YZF-R125 (5D7), will break if the tapping screw is over-tightened.
So, I now use this quick spinner / BE3-Q and handle / AB-53 as much as possible to prevent over-tightening.

This is a little different from the original application, but it is very useful.

3) Uses and specification

① Uses

The tool can be fitted between the ratchet handle and the socket to enable fast turning of the socket.
The grip is shaped so that the angle of rotation can be easily recognized by touch in 90° increments, and the surface is marked in 30° increments to serve as a guide when tightening using the angle of rotation method.
The grip is made of resin and is lightweight.

I often use it with KTC’s hexagonal bit socket BT3-04S etc.

3. Product Review

1) Good points

Prevents damage to spring nuts.
When used with hexagonal bit socket BT3-04S, it fits in the palm of your hand, so you can work with one hand
After more than 12 years of use, the handle has been worn away, but it is still usable
The red color looks great and adds a nice accent.
Of course, it’s also very useful as an original fast turner.
