Knipex 86 06 250 Water Pump Pliers

The Knipex 86 06 250 slip-joint pliers are a general-purpose hand tool designed for gripping, bending and turning a wide range of fasteners and components. Constructed from chrome steel, these pliers combine toughness with dimensional stability. With an overall length of 250 mm and a maximum jaw opening suitable for nuts and fittings up to approximately 52 mm, they offer a balance between reach and leverage for workshop and household tasks. The tool’s weight of roughly 515 g contributes to steady handling and controlled force application.

Advantages

These slip-joint pliers provide a reliable mechanical advantage through a simple, durable joint mechanism that allows two jaw positions. The chrome steel construction resists wear and supports repeated use under load. The 250 mm length delivers a mix of reach and torque, while the jaw geometry is shaped to clamp flat surfaces, round stock and hexagonal fasteners securely. The tool’s mass and ergonomics help reduce hand fatigue during typical grip-and-twist operations.

Suitable for

• Gripping and turning nuts and bolts up to about 52 mm across flats
• Bending and shaping metal or wire in workshop and maintenance tasks
• Holding, pulling or positioning parts during assembly or repair
• General-purpose household, automotive and industrial maintenance jobs

Key specifications

• Material: chrome steel for strength and wear resistance
• Overall length: 250 mm for combined reach and leverage
• Maximum jaw opening: approximately 52 mm suitable for larger fasteners
• Weight: approximately 515 g for stable handling
• Slip-joint design with two jaw positions for adjustable grip

How to use

Open the pliers to the required jaw position and place the jaws over the workpiece so that contact is made on flat or appropriate surfaces of the fastener. Adjust the slip joint to the nearer of the two positions to obtain secure engagement; close the handles firmly to apply force. For turning nuts or bolts, position the jaws square to the flats to minimise slippage and apply steady torque. When gripping round or irregular shapes, align the jaws to maximise contact area. After use, clean any debris from the joint and store the pliers in a dry place to limit corrosion.

Recommendations

Use the Knipex 86 06 250 within its mechanical limits: avoid using it as a hammer, do not exceed the maximum jaw capacity, and do not use the pliers on live electrical circuits. Regularly inspect the joint and cutting surfaces (if present) for wear and keep the tool clean and lightly lubricated to ensure long service life.
