Adjustable Tongue-and-Groove Pliers AWTools AW31157BL 250 mm Black Line

Adjustable tongue-and-groove pliers AWTools AW31157BL 250 mm Black Line are designed for gripping, turning and holding pipes, fittings and fasteners in plumbing, mechanical and general maintenance tasks. The tool features an adjustable jaw position to accommodate varied diameters, offering leverage and a secure bite on round and flat workpieces. The 250 mm length balances reach and control for typical workshop and household applications.

Advantages

The pliers provide a reliable grip and adjustable jaw spacing that enables quick size changes without slipping. A hardened gripping surface improves contact with metal and plastic components, while the ergonomic handle profile increases user control during forceful operations. Compact overall length allows access in confined spaces where larger wrenches would be impractical.

Suitable for

• Plumbing: tightening and loosening pipes, fittings and connectors
• Mechanical repairs: holding nuts, bolts and irregular-shaped parts
• General maintenance: assembly, disassembly and adjustment tasks
• DIY projects at home requiring variable jaw positions and leverage

Key specifications

• Tool type: adjustable tongue-and-groove pliers
• Overall length: 250 mm
• Jaw adjustment: multiple groove positions for variable diameters
• Handle: ergonomic profile for enhanced control
• Finish: Black Line surface treatment for corrosion resistance
• Grip surfaces: hardened serrations for secure contact

How to use

Select the appropriate jaw position by sliding the lower handle to the desired groove so the jaws fit the workpiece. Position the pliers so the fixed jaw contacts the workpiece first and the movable jaw clamps securely. Apply steady force using the handles, maintaining alignment to avoid twisting the tool. Release pressure and readjust the jaw position if the diameter changes or if slippage occurs. Regularly inspect the jaw teeth and handle condition to ensure safe operation.

Usage recommendations

Use the pliers within their intended range: avoid excessive torque beyond hand-applied force or using the tool as a hammer. For threaded fasteners, consider using a correctly sized wrench to prevent rounding. Clean and lightly lubricate the pivot area periodically to maintain smooth jaw adjustment and long service life.
