Description
Small brass and aluminum tube nuts reward a light touch. The Snap-on QJRXS22A flare nut head brings that touch to the 11/16 in size. It grips all six flats through a slotted ring and mounts on J-shank (0.425 in) bodies. Snap-on also makes a Y version, the QYRXS22A, so the shank is the real decision here.
Reasons to pick the J shank at 11/16 in
- Finer settings: the QC2I75 adjusts in 0.5 ft-lb steps, and the QC1I200 works in inch-pounds.
- Shorter reach: QJRXS heads sit 2.50 in from the pin to the fastener center, while QYRXS heads sit at 3.00 in.
- Smaller tools: the QC2I75 is 13 in long, whereas Y presets such as the QC3P150 run 23 in.
- No new body: a cabinet already set up for J heads takes this one as it is.
On the other hand, a firm steel fitting may need the Y twin of the QJRXS22A and its agreed rating.
Clearance figures for the Snap-on QJRXS22A flare nut head
Its outside diameter is 1-5/32 in, so the ring needs about 37/64 in of space from the nut center. The head depth is 15/32 in, which helps between stacked fittings. CAT1500i and the source listing give both figures, and the UK brochure agrees on the diameter. Measure the gap around your nut against them before you order.
Confirming the QJRXS22A working limit
Here the sources split. CAT1500i matches the partner listing, yet the UK Torque Brochure prints a higher figure for the same head. We publish neither number until one is confirmed. The Y twin has no such gap, since both catalogs rate it at about 92 ft-lb. So ask Lost in HCM for the confirmed J limit when you request the price.
A CNC lube line with the Snap-on QJRXS22A flare nut head
Picture a machining center with 11/16 in brass nuts on its central lube manifold. The values are low, and the nuts sit close to castings. A technician fits the QJRXS22A to a QC2I75 and sets the maker’s value. Then the slim ring slides onto the nut beside the tube and turns it on six flats. As a result, the soft corners stay sharp for the next service.

QJRXS22A shank and fit FAQ
Why choose the QJRXS22A over the QYRXS22A?
Pick it for light joints, fine J settings and the shorter 2.50 in reach. Pick the Y head for firm steel fittings.
What gap must the QJRXS22A ring clear?
Its O.D. is 1-5/32 in, so allow about 37/64 in from the nut center to the nearest obstacle.
Does the QJRXS22A suit a 17 mm nut?
No. 11/16 in equals 17.46 mm, which leaves too much play on 17 mm flats. Use the metric QJRXSM17A instead.
