ABSTRACT:
A compensating nail chuck includes a driving rod (12) having a yieldable force-transmitting member (34) comprised of a belleville-washer spring system which compresses in size in response to a back force on the driving rod created by driving a nail. A main housing (10) of the chuck has freedom of vertical movement on a chuck bar (26) for a distance equal to a tolerance difference to be compensated for.
