  • Publication number: 20250114917
    Abstract: An adjustable wrench is shown which includes a handle with a terminal end and a grip end, the terminal end defining a lower bolt claw. A tighten handle is coupled to an adjustment knob-nut. The adjustment knob is-nut is rotationally coupled to a jackscrew with the jackscrew being slidably coupled to the handle and is moveable to control the movement of associated upper and central bolt claws. The upper, central and lower bolt claws are adjustable to different sized bolt heads upon terminal or distal movement of the jackscrew. The central bolt claw fits through a slot in the upper bolt claw, the slot defining an inclined ramp surface, with movement of one claw being coupled to movement of the other claw. The claws move cooperatively in reaction to the stationary, lower bolt claw to form a tightly fitted surface for the bolt head. The jackscrew is manually adjusted during adjustment of the wrench to a bolt.
