The Crescent X6 Pass-Thru Adjustable Wrench is a versatile fastening tool that offers multiple fastening options in a single tool design. The traditional 200mm (8in) adjustable wrench has laser etched SAE/MM scales and a wide jaw opening. With a Pass-Thru reversible ratcheting system that works over long threaded rod, where normal ratchets and sockets won&rsquot fit. For pipework, the jaw reverses. Simply back the jaw out, turn it around and re-insert. Serrations on the inside edge form a deep tooth pattern that hold the pipe tight and reduce slipping. Every pass-thru socket replaces one standard and one deep socket. The universal design allows it to fit 6 fastener types Hex, Square, 12 Pt., E-TORX, Rounded Hex and Spline. Sockets are clearly marked for easy identification and have a corrosion-resistant black phosphate finish. Includes 10 Universal Combo Sockets that fit both standard and metric fasteners 3/8in (10mm), 7/16in (11mm), 15/32in (12mm), 1/2in (13mm), 9/16in (14mm), 19/32in (15mm), 5/8in (16mm), 11/16in (17mm), 23/32in (18mm) and 3/4in (19mm).
