[Features] These water pump pliers are a versatile alternative to traditional pipe wrenches and adjustable wrenches. With a multi-groove adjustment system, they are easy to use for quickly loosening stuck or corroded nuts, bolts, and pipes. They also provide reliable clamping and torque for various fasteners and fittings. [High Quality] Crafted from forged and carbon-hardened chrome vanadium steel (CR-V) with a hardness rating of 58 HRC, these channel lock pliers feature a black phosphate coating that protects against rust and corrosion. This ensures strength, durability, and a long lifespan. [Excellent Design] The pliers boast a slim profile and hardened gripping teeth, allowing for a strong grip in tight spaces and enabling one-handed operation. The PVC non-slip rubber handle ensures a comfortable and secure grip during use. [Adjustable Design] The multi-groove ratchet system allows for precise positioning, making it easy to grip any type of surface. You can easily adjust the pliers to fit different sizes required for your specific application. [Wide Application] This set includes three sizes: 7-inch, 10-inch, and 16-inch adjustable tongue and groove pliers, making them suitable for both industrial and home use. They are ideal for applications in automotive, electrical, and HVAC fields. Each set comes with a canvas bag featuring three separate pockets for organized carrying and storage of the pliers.
