The Kincrome reversible gear spanner has all the benefits of standard spanners and more. The strong fine gear ratcheting ring end needs as little as 2.5° of sweep to move the fastener, a standard fixed ring end needs a minimum of 30°, or 12 times the area. Kincrome Gear Spanner ratcheting ring end has a Peripheral Drive™ configuration that virtually eliminates the rounding off of fasteners. The market-leading narrow and thin head, combined with fine gear tooth design makes the Kincrome gear spanner suitable for working in tight and hard-to-access areas where a ratchet and socket will not fit. The reversible mechanism allows you to change the direction of the gears via the switch, and the 13° offset mimics the characteristics of a conventional combination spanner.
