I thought all chucks had this LH threaded screw, or am I wrong?


My Atlas Copco cordless doesn't, and it's not through engineering down
to a price or lack of torque.

How is it locked to prevent the chuck unscrewing in reverse?

Allen or phillips screw down in the bottom of the chuck, threaded into the
shaft. Open the chuck up full wide and you can peer down and see it.
Obviously you have to pull that first.
