What can you do with a 6 jaw that you can't do with 4?

hold a hexagonal part!




Ok, copy all...

Most of the six-jaws I've seen were used in batch-production applications,
where the idea is to minimize distortion while maintaining clamping
integrity. Above all, it was to achieve part-to-part consistency where
tolerances are tight, as they are in almost all automotive and power-tool
applications today.

We used them a lot at Wasino, mostly for turning those automotive and
power-tool parts.
