jackus

jackus refers to a type of hand-held tool used for gripping and turning objects, often pipes or bolts. It typically consists of a pair of adjustable jaws, a handle, and a locking mechanism. The jaws are serrated to provide a strong grip on the object being held. The adjustment is usually made by a screw mechanism, allowing the jaws to be opened or closed to fit various sizes of objects.

This tool is commonly found in plumbing and mechanical trades due to its effectiveness in securing and manipulating pipes and fittings. Its ability to exert significant torque makes it useful for tightening or loosening stubborn connections. Different sizes and configurations of jackus tools exist to accommodate a wide range of applications, from small household repairs to heavy industrial work.

The design of a jackus prioritizes leverage and grip strength. The handle provides a point of leverage for the user to apply force, while the serrated jaws ensure that the tool does not slip. The locking mechanism, when present, allows the jaws to remain fixed at a desired opening, freeing the user's hands for other tasks. While the term "jackus" is sometimes used generically, it is closely related to, and often used interchangeably with, pipe wrenches or monkey wrenches.
