The measured results
Every number below is read straight from the test. Products are listed in the order they finished.
Round 1, undamaged bolt
- 1Irwin Vise Grip Locking Pliers
loosened without slipping, but caused a small amount of damage to the previously undamaged bolt
- 2Stanley Locking Adjustable Wrench
made easy work of it, though the jaws stretched enough at loosening torque to cause damage to the bolt corner
- 3Universal Socket
successfully loosened it, but the internal steel pins caused minor damage to the bolt
- 4Maxpower Swedish Pipe Wrench
loosened it, but the aggressive teeth caused a lot of damage to the bolt, and the teeth themselves also experienced some wear
- 5Duratech Universal Wrench
loosened without a problem, though the jaws are soft and showed quite a bit of damage; very minor damage to the bolt
- 6Crescent X6
made easy work of it
- 7Bionic Wrench
got the job done, described as needing a firm ('Bionic') grip to operate well
- 8Magic Wrench
the only one of the 16 initial tools that was NOT able to loosen the undamaged bolt at all
- 9GripTite GT Pro
made very easy work of it, with a very tight grip as the name implies
- 10Olsa Tools Bolt Extractor Offset Wrench Set
easily removed it, leaving the bolt looking almost as good as new with only a small amount of corner damage
- 11Rocket Socket
did just fine, though it did cause some damage to the bolt
- 12GearWrench
more than enough grip; the bolt still looked as good as new
- 13Capri Tools
maintained very good grip, but the wrench applies pressure away from the corners, causing bolt damage; the chrome plating on the wrench itself was seen crumbling
- 14MichaelPro
made easy work of it and held up well with no visible damage to the wrench
- 15Metrinch
performed just fine, though the wrench has a lot of taper and the spline only applies pressure to about 70% of the bolt head
- 16Snap-on
made very easy work of it; the bolt began loosening at 63 ft-lb with more than enough contact area to avoid any damage
- 17Matconot tested

- 10Olsa Tools Bolt Extractor Offset Wrench Set
more than enough grip to remove the badly rounded fastener
- 11Rocket Socket
made easy work of it after a few light hammer taps
- 12GearWrench
repositioned itself to take advantage of flat areas on the bolt

before coming off the bolt

How it was tested
- round 1: closed-end wrench performance on an undamaged, partially rounded, and completely rounded 7/16 in grade 8 fine-thread bolt torqued to 78 ft-lb (only 7 of the 16 initial tools loosened the partially rounded bolt; only the Maxpower pipe wrench and Rocket Socket loosened the completely rounded bolt)
- round 2: open-end wrench maximum torque on an undamaged and a partially rounded grade 8 bolt (ft-lb)
- round 3: six-sided-contact tool maximum torque on an undamaged and a partially rounded grade 8 bolt (ft-lb)
- tool size/footprint for tight-space access (closed-end and open-end diameters in inches)
- subjective tool durability rating
