## Summary description

The Knipex 40 14 250 locking pliers are made of durable chrome and zinc steel, with a maximum pipe diameter of 4.5 cm. They measure 250 mm in length and weigh 600 g, providing a strong grip for various applications. Ideal for professionals and DIY enthusiasts alike, these pliers ensure reliability and ease of use.

## Long description

The Knipex 40 14 250 locking pliers are 250 mm long heavy-duty pliers designed for secure clamping of round, profile and flat materials. Constructed with a rolled steel body and gripping jaws made from chrome vanadium electric steel, the tool combines mechanical strength with corrosion-resistant bright zinc plating. An adjustment screw and a release lever allow one-hand operation and precise jaw setting, while the toggle lever mechanism delivers high clamping pressure for demanding tasks where a reliable hold is required.
Advantages
These locking pliers provide a firm, repeatable grip on pipes and profiles up to the specified maximum diameter thanks to the pivoting jaw design. The combination of a high-strength rolled steel body and forged gripping jaws offers long service life under frequent use. Bright zinc plating improves resistance to corrosion and wear, and the integrated adjustment screw and release lever enable rapid single-handed adjustment and release during installation or repair work.
Suitable for
 Holding and clamping round pipes and tubes during welding or assembly
 Securing profile or flat stock for cutting, filing or grinding
 Temporary fastening of components during maintenance and repair
 Automotive and plumbing work that requires strong clamping force
Key specifications

 Weight: 600 g
 Body material: rolled high-strength steel
 Jaw material: chrome vanadium electric steel, forged

 Operation: one-hand operation with adjustment screw and release lever

How to use
Open the jaws and turn the adjustment screw to set the initial jaw gap larger than the workpiece. Position the pliers so the pivoting jaw aligns with the surface to be held and squeeze the handles until the toggle engages and the jaws lock. To release, operate the release lever with one hand while holding the pliers steady. For repeated operations, fine-tune the adjustment screw to achieve the required clamping force and jaw alignment for the specific material and thickness.
Usage recommendations
Use these locking pliers on clean contact surfaces to maximize grip and avoid slipping. Do not exceed the specified maximum diameter and avoid using the tool as a hammer or for prying. Regularly inspect the jaws and the adjustment mechanism for wear and lightly lubricate the pivot and screw threads to maintain smooth one-hand operation.
