Description
A nut that measures 2-1/8 in across flats rarely holds a light setting. The Snap-on QYO68ARTH open end head gives that size a thin jaw on the Y (0.560 in) shank. Its working limit is 160 ft-lb, near 217 N·m. So it can finish jam nuts that a 60 ft-lb J head would leave short.
Rating, shank and spacing of the QYO68ARTH
| Item | QYO68ARTH |
|---|---|
| Jaw opening | 2-1/8 in (53.98 mm) |
| Shank | Y (0.560 in) |
| Maximum working torque | 160 ft-lb (about 217 N·m) |
| Fastener center to retaining pin | 3.00 in (QYO series) |
The partner title mentions a square drive, but 2-1/8 in is the jaw size. The QYO68ARTH takes no sockets.
Why the Y shank matters at 2-1/8 in
Snap-on also lists a thin QJO68ARTH at this size. That J head stops at 60 ft-lb, while the QYO68ARTH reaches 160 ft-lb. Because the jaw widths match, the drawing value decides between them. If the joint calls for more than 60 ft-lb, the Y head is the only thin choice at 2-1/8 in.
Bodies matched to the Snap-on QYO68ARTH open end head
The QC3P150 preset spans 30-150 ft-lb, so its full scale stays under the head limit. Next, the QD3IN200B reads 40-200 N·m, and 200 N·m also sits below 217 N·m. In contrast, the QC3P200 preset climbs to 200 ft-lb. Therefore cap that body at 160 ft-lb whenever this head is on it. For values under 100 ft-lb, the CTECH2Y100A ControlTech body is another Y option.
Cylinder rod lock nuts and the QYO68ARTH
Hydraulic cylinders often lock a rod eye or clevis with a large jam nut. The rod passes through the nut, so a socket cannot go on. Then the thin QYO68ARTH jaw slides between the nut and the rod end. As a result, both cylinders on a press or lift can get the same measured lock torque. Still, free an old nut with a plain wrench first, because Snap-on warns against breaking fasteners loose with torque tools.

Before ordering the QYO68ARTH
Does Snap-on make a J-shank 2-1/8 in thin head?
Yes, the QJO68ARTH. It has the same jaw size, but its limit drops to 60 ft-lb.
Which thin Y heads sit next to the QYO68ARTH?
On the smaller side sits the 2 in QYO64ARTH, and the 2-1/4 in QYO72ARTH sits above. Each one also carries 160 ft-lb.
Can the QYO68ARTH work on a 54 mm metric nut?
A 2-1/8 in jaw equals 53.98 mm, so it is an inch tool. Measure any metric nut, and ask Lost in HCM about a metric jaw if the fit is loose.
