21 mm Flex Ratcheting Combination Wrench
Item #WRN57121
- Box end head pivots 180 degrees to easily get around obstructions
- 6-point box end snugly fits hex-shaped fastener heads and resists slipping off while you work
- Box end opening is designed to grip flat sides of fastener heads, not corners, to prevent round-off
- 72-tooth ratchet gear needs only a 5-degree working swing arc
- Open end is angled 15 degrees so the wrench can be flipped over to engage fasteners twice as often in tight spaces
