Open wrenches, also called open-end spanners, slide onto nuts and bolts from the side. They are quick to use on pipe fittings, fuel lines and fasteners where a box wrench cannot fit over the end.
How to choose an open wrench
- Double open end: most open wrenches have two sizes, one on each end, so a set covers many sizes.
- Head angle: the angled head lets you flip the wrench to keep turning in tight spaces.
- Flare nut wrench: for brake, fuel and aircon lines, a flare nut wrench grips more of the nut.
- Loose or set: loose wrenches replace single sizes. Sets cover 6mm to 32mm or 1/4" to 1-1/4".
