Features:Sidchrome has been an Australian icon in the industry since 1942. For generations Australians and New Zealanders have put their trust in Sidchrome sets. - When you add a Sidchrome Socket Set to your workshop or site Tool Chest you are gaining flexibility and premium quality tools, all designed to give you The Professional Advantage . Sidchrome Torque - Plus; All standard and deep hand sockets and ring spanners feature the TORQUEPLUS fastening system. This unique system allows greater contact with the flats of fasteners, providing greater torque to enable easier fastening. Conventional sockets damage fasteners by concentrating forces on the corners. Sidchrome TORQUEPLUS sockets and ring spanners spread the force over a larger contact area, reducing the rounding off and extending fastener life. Sidchrome TORQUEPLUS sockets are particularly useful on worn or rounded fasteners. Sidchrome Anti - Slip Design (ASD) - easier and safer; Sidchrome open end spanners and the open end of combination spanners (up to 32mm or 1 1/4") feature the innovative ANTISLIP DESIGN (ASD). ANTISLIP DESIGN features a locking groove to prevent slippage and knuckle injury. The unique arc design increases surface contact by over 400%. This means increased torque is applied to the fastener, resulting in fewer rounded fasteners, and a much safer jobs. - Specifications:Part No - Includes: 1/2 Drive Sockets & Accessories 19 8, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 27, 30, 32mm 15 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16, 1, 1-1/16, 1-1/8, 1-3/16, 1-1/4 2 Spark Plug: 5/8 & 13/16 3 Ratchet, 375mm Flex handle, Universal Joint, 2 Extension: 125 mm & 250mm 1 200mm Adjustable Wrench;
