The Facom Auto Lock Grip Pliers have a patented automatic closing mechanism that automatically adjusts the jaws to the work piece, regardless of it size, with the same pressure. This makes them ideal for saving time and for production work. The pliers are suitable for industrial and automotive production and maintenance applications. They are made from chrome-molybdenum steel, with treated jaws for a longer working life. They have a non-slip, chequered handle and allow one-handed unlocking by the internal opening lever.Specifications:Length: 250mm (10in).Capacity: 38mm.
