Construction and operation of a basin wrench
– Basin wrench consists of a long shaft with asymmetrical jaws
– Jaws are joined with a pivot pin
– One jaw is fixed relative to the shaft, while the other is curved
– Some basin wrenches have a spring-loaded curved jaw for automatic gripping
– Transverse handle can be adjusted for tight spaces or increased leverage
Jaw assembly rotation
– Fixed jaw is attached to the shaft with a pivot pin
– Jaw assembly can rotate about an axis perpendicular to the shaft
– Allows the tool to apply torque in clockwise or counter-clockwise direction
– Mechanical stops limit rotation to 180°
– Jaws are automatically held against the stop by gravity when shaft is vertical
Torque and grip
– When shaft is rotated, jaws increase grip on the object
– Torque can be applied without slippage
– Basin wrenches allow for increased torque as shaft torque increases
– Curved jaw trailing the pivot pin enhances grip
– Grip on the object can be adjusted by rotating the shaft
Availability and options
– Basin wrenches are available with fixed-length and telescopic shafts
– Telescopic shafts allow for increased reach
– Fixed-length shafts are suitable for standard applications
– Different sizes and designs of basin wrenches are available in the market
– Basin wrenches can be purchased from various retailers and online stores

A basin wrench, sometimes called a sink wrench, is a plumbing tool which is used in confined spaces to turn fasteners and pipes that would be difficult or impossible to reach with a plumber wrench or other types of wrenches. For example, the threaded nuts used to secure faucets to sinks are often located in deeply recessed places that can only be accessed with a basin wrench.
