Description
A 17 mm tube nut sits at a size where Snap-on offers both a J and a Y flare head. The Snap-on QYRXSM17A flare nut head is the Y-shank choice, with a slotted 6-point ring and an 83 ft-lb rating, about 113 N·m. So it suits teams that run Y bodies or need more headroom than the J version gives.

| Item | Value |
|---|---|
| Shank | Y (0.560 in) |
| Size | 17 mm, 6-point, slotted ring |

Choosing between the 17 mm J and Y heads
Snap-on also lists a J-shank 17 mm head, the QJRXSM17A, on the same 29 mm by 11 mm size row. However, both Snap-on documents rate the J head lower than the QYRXSM17A. The J head also sits closer to the pin, at 2.50 in instead of 3.00 in. So pick the Y head when your fitting spec runs high, or when your bench already uses Y bodies.
Wrench bodies that accept the Snap-on QYRXSM17A flare nut head
| Body | Type | Range |
|---|---|---|
| QC3P150 | Preset | 30-150 ft-lb |
| QC3P200 | Preset | 40-200 ft-lb |
| QD3IN200B | Adjustable, dual range | 40-200 N·m (37-140 ft-lb) |
| CTECH2Y100A | ControlTech electronic | 5-100 ft-lb |
Every one of these bodies reaches past 83 ft-lb. So the head, not the body, sets your ceiling. Keep the setting at or below 83 ft-lb whenever the QYRXSM17A is on the wrench. In addition, follow the body manual on head length, because the Y flare heads sit 3.00 in from the pin.
Neighbors in the Y flare range
The QYRXSM16A sits one size down at 75 ft-lb, and the QYRXSM18A sits one size up at 94 ft-lb in CAT1500i. Since a 6-point ring needs a snug fit, measure the nut across its flats before you choose. A burr inside the slot can scar a soft brass nut, so dress or replace a damaged QYRXSM17A.
