The ICON™ Professional Double Box Flex Ratcheting Wrench Set is precision-machined for a perfect non-slip grip, and features a 90 tooth reversible ratcheting box end for easy fastener engagement without slippage and prevents fastener round-off, resulting in more efficient work. We use a premium chrome vanadium steel, with a tough and durable polished chrome finish that offers superior rust and corrosion resistance and prevents grease build-up. The flex box ends make it easier to work in tight spaces and reach around obstructions. Designed with comfort and efficiency in mind, the ICON™ Professional Double Box Flex Ratcheting Wrench offers a balanced handle design for a comfortable secure grip, and is backed by a hassle-free manufacturer’s lifetime warranty.
