GearWrench 12mm metric combination wrench with a 72-tooth ratcheting box end and a standard 12mm open end. The 72-tooth ratchet needs only 5 degrees of arc swing to move a fastener, half the swing of a 30-degree standard wrench, so it works in tight spaces where a conventional combination wrench cannot turn.

• 72-tooth ratcheting box end - 5 degree minimum swing arc
• Surface Drive off-corner loading reduces fastener rounding
• 12mm open end for standard non-ratcheting use
• Thin head and beam for access in confined areas
• Size 12mm stamped on both ends of the beam for quick identification
• Alloy steel construction, bright full polish chrome finish
• Meets or exceeds ASME and ANSI specifications

Tip: Slide the box end onto the fastener and rock the handle in short strokes - the 72-tooth ratchet engages on every 5 degrees of motion. Flip the wrench to reverse direction.
