Key Features

• High-Carbon U.S. Steel Construction: Built from robust C1080 high-carbon U.S. steel, these pliers provide the strength and durability essential for sustained professional use in automotive shops, fleet maintenance, and industrial settings. They are also specially coated for ultimate rust prevention.
• PermaLock® Fastener: The patented Channellock PermaLock® design securely maintains the pivot joint, preventing loosening and ensuring the pliers retain their tight, reliable action over extended periods of heavy use, eliminating nut and bolt failure.
• Right-Angle, Laser-Hardened Teeth: Equipped with aggressive, laser-hardened teeth set at a right angle, these pliers deliver a tenacious bite on fasteners, fittings, and irregularly shaped components, minimizing slippage and potential rounding.
• Undercut Tongue-and-Groove Design: This precise, patented design keeps the jaws consistently aligned even under significant load, providing a stable, no-slip grip and controlled adjustment, particularly when working from awkward angles.
• SAFE-T-STOP® Feature: The lower jaw design combines with an expanded reinforcing rib to prevent the handles from contacting each other, helping to prevent finger pinch and extending the tool's longevity.

Applications

• Automotive Service: Ideal for gripping and turning fittings, hose ends, clamps, and brackets on passenger vehicles, light trucks, and fleet vehicles during routine maintenance and repair.
• Industrial and Mechanical: Suitable for maintenance tasks on machinery, adjusting valves, and general plant equipment where a secure, non-slip grip on components is critical for safe and efficient operation.
• Plumbing and HVAC: Effective for adjusting and holding pipe, unions, and threaded fittings during the assembly or disassembly of plumbing systems and HVAC units.
