<p>An open-end wrench (6) includes a handle portion (61) and a containing portion (62). The containing portion (62) includes a first jaw (93) and a second jaw (94). The jaws (93,94) define a containing groove (65) configured to receive a workpiece. The open-end wrench (6) also includes a chuck (64), a resilient member (98) and, in a preferred embodiment, a stop protector (99). The chuck (64) is slidably mounted on the second jaw (94). The resilient member (98) is operatively disposed between the second jaw (94) and the chuck (64). The resilient member (98) is configured to bias the chuck (64) towards the handle portion (61). The protector stop (99) interacts between the second jaw (94) and the chuck (64) to limit the extent of relative movement therebetween to limit the extent of compression of the resilient member (98).</p> |
