Description
Some nuts sit where neither a socket nor a ring can reach. A jam nut on a threaded rod is one case, and a fitting on a pipe run is another. The Snap-on QJO22ARTH60 open end head slides onto the flats from the side, so you can torque an 11/16 in hex without taking the line apart.

Bodies that take the QJO22ARTH60
The head needs a body with a J shank. In Snap-on’s range, that includes the QC1I200 and QC2I75 adjustable bodies, the J-shank preset bodies, and the QD2IN50A and QD2IN100A dual-range bodies. Because it keeps the standard 2.50 in J spacing, the dual-range bodies need no adjustment calculation. However, watch the top of the scale. The QC2I75 reaches 75 ft-lb, so hold the setting at 60 ft-lb or less with this head.
When an open end beats a ring
- The fastener sits on a tube, cable or rod that you cannot disconnect.
- A thin jaw must slip between a nut and a close neighbor, such as a lock nut pair.
- You need to place the head from the side rather than from above.
On the other hand, an open end bears on only two flats. For soft tube nuts, therefore, Snap-on’s 6-point flare nut heads hold more of the hex. In the J range, the QJRXS22A covers 11/16 in at the same 60 ft-lb.
Care tips for the QJO22ARTH60
Seat the jaws of the Snap-on QJO22ARTH60 open end head fully on the flats before you pull, and keep the pull in the plane of the head. Also inspect the jaw tips for spread or burrs, because a worn jaw can round a nut corner. Then follow Snap-on’s advice on periodic recalibration of the body.

QJO22ARTH60 FAQ
Is this a square drive head?
No. The partner listing title mentions a square drive, yet Snap-on’s catalog places the QJO22ARTH60 in its thin open end table with an 11/16 in opening.
Will it go on a Y-shank body?
No. It carries a J shank only. Snap-on’s thin open end table also shows no Y-shank head at 11/16 in, so this size needs a J body.
How much torque can it carry?
Snap-on gives 60 ft-lb as the maximum working torque. Keep every setting at or below that figure.
