The GearWrench Flex head wrench is built with spring washers which keep the head tight even after years of use. It has a sleek head design, which flexes and enables access to tight spots. It has a very unique wrench beam, and is slightly serrated (etched) on one side, so the mechanic can feel which way to pull.
The ratcheting box end needs only 5 degrees of sweep needed to move a fastener
Surface drive nearly eliminates fastener rounding
