## Long description

Knipex 40 04 250 locking pliers are 250 mm long hand pliers engineered for secure gripping of pipes, tubes and hexagonal fasteners. The tool combines a wide jaw opening with a precise locking mechanism to clamp workpieces up to a pipe or tube diameter of 35 mm and nuts up to 32 mm across flats. With a robust steel construction and a weight of approximately 521 g, these locking pliers are intended for plumbing, mechanical repair and assembly tasks where reliable clamping and turning force are required.
Advantages
The tool offers a strong locking function that maintains clamping force without continuous hand pressure, enabling safer and steadier handling of pipes and nuts. Its jaw geometry and adjustable release allow gripping a variety of round and hexagonal profiles within the specified maximum diameters. The durable construction resists wear during repeated clamping and provides stable torque transfer when turning fasteners or holding parts in position.
Suitable for
 Gripping and holding metal pipes and tubes up to 35 mm diameter
 Clamping and turning nuts and bolts up to 32 mm across flats
 Plumbing installations and repairs where secure pipe hold is required
 Mechanical assembly, maintenance and repair tasks requiring temporary clamps
Key specifications
 Overall length: 250 mm
 Maximum pipe/tube diameter: 35 mm
 Maximum nut size (across flats): 32 mm
 Tool type: locking pliers (vice-grip style)
 Weight: approximately 521 g
 Material: hardened steel construction (mechanical tool)
How to use
Adjust the jaw spacing by turning the adjustment screw until the jaws match the diameter of the pipe, tube or nut to be gripped. Position the jaws around the workpiece and squeeze the handles together until the locking mechanism engages and holds the item firmly. To release, pull the release lever or press the release catch while controlling the tool to avoid sudden movement of the clamped part. Use steady, controlled force when turning fasteners to prevent slippage and protect the jaw surfaces.
Usage recommendations
Use these locking pliers within the specified maximum diameters to ensure safe clamping and avoid overloading the locking mechanism. Inspect jaws for wear and clean contact surfaces regularly; apply light lubrication to the pivot and adjustment screw as part of routine maintenance. For tasks requiring strong torque on fasteners, combine the pliers with correct-sized wrenches where appropriate to prevent damage to nut faces.
