The Ratcheting Wrench combines the benefits of a ratchet and an open end/ring spanner. The strong fine gear ratcheting box end needs as little as 5°of sweep to move a fastener where a standard fixed box end needs a minimum of 30°or 6 times the area. The ultra small head and shank design allow it into the tightest of places, where a ratchet and socket will not fit. The GearWrench's fully hardened metal construction is extremely strong, meeting or exceeding DIN and ANSI torque specifications for a standard fixed style box end wrench. The Surface Drive design on both the ratcheting box end and the open end virtually eliminates the rounding of fasteners' hex heads.
