Product Specification :
A Pipe Wrench is an adjustable heavy-duty wrench designed to grip and turn threaded pipes and pipe fittings. Unlike a standard adjustable wrench, it features serrated teeth and a unique "hook jaw" design that provides a self-locking grip when pressure is applied to the handle.

1. General Characteristics
- Design: Features a heavy handle with a fixed jaw and a movable "hook jaw" adjusted by a large knurled nut.
- Self-Gripping Mechanism: The hook jaw is designed with a slight "play" or wiggle; as torque is applied, the jaws pivot and bite deeper into the pipe.
- Directional Use: It is a one-way tool. It grips when pulled in the direction of the jaw opening and releases when moved in the opposite direction (acting like a ratchet).

4. Specialized Variations
- Offset Pipe Wrench: The head is angled at 90° to the handle, allowing for use in tight corners or parallel to walls.
- End Pipe Wrench: Designed for pipes close to walls or in narrow trenches.
- Strap Wrench: Uses a nylon strap instead of teeth; used for polished or plastic pipes (PVC) to prevent scratching.
- Chain Wrench: Uses a heavy-duty chain to wrap around very large diameter pipes or irregular shapes.
