## Long description

The Knipex 40 04 250 locking pliers are a durable hand tool engineered for secure clamping of round and flat workpieces up to a maximum pipe diameter of 3.5 cm and nut size of 3.2 cm. At 250 mm overall length and weighing 521 g, this model balances size and handling for tasks that require firm grip and leverage. Constructed from hardened tool steel with a corrosion-resistant finish, these locking pliers provide reliable mechanical locking and repeatable performance in workshop and field environments.
Advantages
These locking pliers combine a compact 250 mm length with a strong locking mechanism to maintain grip without continuous hand pressure. The jaw profile is shaped to hold round pipes and nuts securely, while the adjustment screw allows fine tension settings for different diameters up to 3.5 cm. Robust construction and a protective surface finish increase resistance to wear and environmental exposure, supporting long service life under regular professional or home use.

How to use
Open the jaws using the release lever and adjust the screw to approximate the required jaw opening for the object to be gripped. Position the jaws around the pipe, nut or workpiece and squeeze the handles until the locking mechanism engages. The pliers will hold the workpiece securely; to release, press the release lever to disengage the lock. For finer control, readjust the screw tension and test the grip on scrap material before use on the actual component.
Usage recommendations
Use the pliers within the specified capacity limits: do not attempt to clamp pipes or fasteners larger than 3.5 cm diameter or nuts beyond the indicated width. Avoid using the tool as a hammer or lever beyond its intended purpose. Keep the adjustment screw clean and periodically apply a light lubricant to the pivot for smooth operation and to extend service life.
