Mac Tools offers the Mac Edge seven-piece SAE (SRWFQ67K.) and seven-piece Metric (SRWMFQ67K) FLEX2 Combination Ratcheting Wrench Set. This product marries the Mac Edge non-slip grip technology, that can remove fastener heads up to 70% rounded, with the double joint flexible box end design, allowing these wrenches to be used at multiple offset angles. The double flex joint provides two times more access to hard-to-reach fasteners - 180° x 2 range of motion. These ratcheting wrenches are built for the toughest job - a meatier shank with a full polish nickel chrome surface enables the wrenches to perform under high torque applications while maintaining a comfortable grip. Mac Tools open end ratcheting wrenches also have a unique "knuckle-saver" open-end non-slip design, preventing damage to both the bolt and your hands.
