ABSTRACT:
An adjustable socket for removing threaded fasteners has a split collet socket, a collet ring and an outer barrel. The split collet ring has at least two fingers. The collet ring is mounted about ends of the fingers. The outer barrel threadably engages the split collet socket and frictionally engages the collet ring. Rotating the barrel relative to the split collet socket in one sense urges the collet ring to close the fingers for gripping a head of the threaded fastener. Continued rotation of the barrel in the one sense increases the grip and applies a torque to the threaded fastener for removal thereof. Counter rotation of the barrel relative to the split collet socket relaxes the collet ring allowing removal of the head of the threaded fastener.
