Description
Fifteen-sixteenths of an inch is a hex size found on mid-size hydraulic and fuel fittings. The Snap-on QYRXS30A flare nut head fits it with a 6-point ring on a Y shank. Snap-on rates the head at 146 ft-lb, so it covers firm joints that a J head cannot reach.
The 15/16 in head by the numbers
- Size: 15/16 in, 6-point.
- Shank: Y (0.560 in).
- Maximum working torque: 146 ft-lb, about 198 N·m.
- Outside diameter: 1-1/2 in; head depth: 19/32 in.
- Fastener center to retaining pin: 3.00 in (QYRXS series).
Three 15/16 in options from Snap-on
| Head | Profile | Shank | Max torque |
|---|---|---|---|
| QJRXS30A | 6-point | J | 60 ft-lb |
| QYRXS30A | 6-point | Y | 146 ft-lb |
| QYRX30A | 12-point | Y | 146 ft-lb |
The J head, however, suits light fittings only. Between the two Y heads, the Snap-on QYRXS30A flare nut head holds soft or worn nuts better, thanks to its 6-point profile. The 12-point head, meanwhile, finds a grip in a smaller swing.
Matching a body to the Snap-on QYRXS30A flare nut head
Before you buy a body, check its range against the 146 ft-lb rating. The QD3IN200B tops out at 140 ft-lb, so its whole scale sits inside the head limit. The QC3P150 runs to 150 ft-lb, and the QC3P200 to 200 ft-lb. With either preset, therefore, keep the setting at 146 ft-lb or lower. The CTECH2Y100A stops at 100 ft-lb, well under the rating. The head also keeps the 3.00 in Y spacing that Snap-on’s dual-range bodies assume.
Where 15/16 in fittings show up
- Hydraulic tube nuts on forklifts and loaders.
- Fuel and oil lines on diesel generator sets.
- Hydraulic lines on stamping and forming presses.
If your nut sits between sizes, Snap-on’s neighbors to the QYRXS30A are the QYRXS28A at 7/8 in and the QYRXS32A at 1 in.
