The idea of an indexing box-end — complete with GearWrench’s well-known fine-toothed ratcheting system — makes a lot of sense. Believe me, there’s nothing more frustrating than trying to get at a damn bolt or nut that’s just a little bit off from any angle you can possibly reach with a straight wrench. (Pick yourself up a set of deep offsets, too.) But hey, GearWrench’s double box-ends go to 11, man. Both ends index.
As you can see in the infographic above (courtesy of GearWrench, of course), you get 13 locking positions. This means that rather than simply flopping around like a some similar wrenches, you can lock this one in place, stick it down in the engine compartment, pull it back out and move it over a notch or two, and repeat until you can finally latch it on the buried fastener. GearWrench has been great about including this kind of indexing system on almost all their special-access tools, which simply rocks.
Other than their 13-year-old-gymnast-like flexibility, they’re pretty much just standard box-end ratcheting wrenches. They’re sold individually or in a single six-piece set with six size combinations: 8 and 10 mm, 11 and 12 mm, 13 and 14 mm, 15 and 16 mm, 17 and 18 mm, and 19 and 21 mm. Expect to pay around $80 for the set or around $30 apiece for open stock wrenches. And if you want to see them in person, it’s a fair bet you can find them at your local Sears.
