Model : SATA 09925 19 Pc. Metric Double Ratcheting Wrench Tray Set 

Features : 

Strong fine gear ratcheting box end needs as little as 5° of sweep to move a fastener, a standard fixed box end needs a minimum of 30° or 6 times the area. Ultra small head shank design allows it into the tightest of places, places where a ratchet and socket will not fit. The ratcheting box end comes with Surface Drive configuration that nearly eliminates fastener rounding. With the special accessory adapters, it becomes a fine gear ratchet that does not require special sockets.
