Description
Snap-on’s flare nut tables skip some sizes, and 1-3/16 in is one of the gaps. There is no 6-point head and no ratchet at this size. So the Snap-on QYRX38A flare nut head is the only slotted ring for a 1-3/16 in tube nut in those tables. It pairs a 12-point ring with the Y shank and the standard 3.00 in Y spacing.
Where the Snap-on QYRX38A flare nut head sits in the range
- Opening: 1-3/16 in, 12-point, slotted.
- Shank: Y (0.560 in).
- Pin-to-nut spacing: 3.00 in, the QYRX standard.
- Smaller neighbor: QYRX36A at 1-1/8 in.
- Larger neighbor: QYRX40A at 1-1/4 in.
The catalog, the UK brochure and the listing disagree on rating, width and depth. Therefore we omit all three for the QYRX38A. Lost in HCM confirms them for your order.
No 6-point, no ratchet at 1-3/16 in
Snap-on’s 6-point inch flare heads stop at 1-1/8 in. Likewise, the ratcheting table jumps from 1-1/8 in straight to 1-1/4 in. As a result, a 1-3/16 in nut leaves two Snap-on choices: the QYRX38A ring or the QYO38A open end head. The ring wraps the whole nut, so it is the better pick for final torque on a tube nut. The QYO38A suits only spots where a ring cannot pass.
Inch nut or 30 mm metric?
A 1-3/16 in hex equals 30.16 mm, very close to a 30 mm hex. So the QYRX38A may slide onto a 30 mm nut with a slight wobble. Even that small play can round a soft fitting under load. Therefore use metric tools on metric nuts, and keep the Snap-on QYRX38A flare nut head for true inch sizes.

Large tube nuts often carry high values, so check your spec against both the body range and the confirmed head limit. Then work to the lower of the two every time.
