Description
Some heads outrank the wrench that drives them. The Snap-on QYRXS26A flare nut head is one, with a rating near 117 ft-lb, or about 159 N·m. A common Y ControlTech body stops at 100 ft-lb, so the body becomes the limit. The head itself is a 13/16 in 6-point ring that slips over the tube and grips all six flats.
Body limits with the QYRXS26A
The CTECH2Y100A reads 5 to 100 ft-lb, so it can never reach the head rating. That leaves a margin for light and medium joints. By contrast, the QC3P150 preset spans 30 to 150 ft-lb, and the QC3P200 runs to 200 ft-lb. On those bodies, the setting must stay under 117 ft-lb. Likewise, the QD3IN200B covers 40 to 200 N·m, so keep it below 159 N·m.
Three Y heads for a 13/16 in nut
| Head | Grip | Rating in CAT1500i |
|---|---|---|
| QYRXS26A | 6-point slotted ring | 117 ft-lb |
| QYRX26A | 12-point slotted ring | 117 ft-lb |
| RTWH52YSL | 12-point ratcheting ring | Not printed |
Choose the QYRXS26A for worn or soft nuts, because six flats carry the load. The 12-point head re-seats in smaller steps when the swing is short. Meanwhile, the ratchet speeds up run-down but has no printed rating.
Size and fit of the Snap-on QYRXS26A flare nut head
Both catalogs print an outside diameter of 1-5/16 in for the 13/16 in row. So the ring needs about 21/32 in of clear space from the nut center. Also, 13/16 in equals 20.64 mm, so it will not suit metric 21 mm nuts. For those, Snap-on lists the metric QYRXSM21A on the Y shank.
Mobile equipment work for the Snap-on QYRXS26A flare nut head
Forklift and loader fleets often include US-built machines with inch steel tube lines. A 13/16 in nut near a valve block may need a firm value that a J body cannot reach. In that case, the QYRXS26A on a QC3P150 tightens it in one steady pull. Just keep the preset below the head rating, and take the value from the machine manual.

QYRXS26A rating and fit questions
Why does the CTECH2Y100A not reach the head limit?
Its scale ends at 100 ft-lb, while the head is rated near 117 ft-lb. So the head always keeps a margin on that body.
Is the J-shank QJRXS26A an equal option?
Not for firm joints. Snap-on’s sources disagree on its rating, while both agree on about 117 ft-lb for this Y head.
How wide is the QYRXS26A?
Its outside diameter is 1-5/16 in, in both CAT1500i and the UK brochure.
