Description
In Snap-on’s metric box end table, the Y column begins at 14 mm. The Snap-on QYXM14A box end head is that first Y ring. It wraps a 14 mm hex on twelve points and locks into Y-shank (0.560 in) torque bodies. So a station that runs Y wrenches can handle small 14 mm work without a second handle.
What the brochure and listing agree on for the QYXM14A
- Ring: closed, 12-point, 14 mm across flats.
- Shank: Y (0.560 in).
- Rated limit: 1,400 in-lb, which is about 117 ft-lb or 158 N·m.
- O.D. 21 mm and head depth 9 mm.
- Fastener center to retaining pin: 3.00 in, as for every QYXM ring.
The UK torque brochure and the partner listing agree on each figure. With both sources in step, the QYXM14A rating is safe to write on a work instruction.
Choosing between the J and Y rings at 14 mm
Snap-on also makes a J ring at this size, the QJXM14A, with a 900 in-lb limit. Thus the Y version carries roughly half again as much. X rings, meanwhile, only start at 17 mm in the brochure. In practice, that extra margin matters less than the body you own. Pick the Snap-on QYXM14A box end head when your cabinet holds Y bodies, and the QJXM14A for a J kit.
Setting Y bodies under the Snap-on QYXM14A box end head limit
| Y body | Scale | Fit with a 117 ft-lb ring |
|---|---|---|
| CTECH2Y100A | 5-100 ft-lb | Whole scale sits below the limit |
| QC3P150 preset | 30-150 ft-lb | Cap the preset at 116 ft-lb |
| QD3IN200B | 37-140 ft-lb | Lock out the top of the scale |
| QC3P200 preset | 40-200 ft-lb | Cap it far below its top |
Most 14 mm joints call for much less than 117 ft-lb. A steel M10 bolt with a 14 mm head, for example, usually needs far less. So the QYXM14A is rarely the weak link, and the low end of the body matters more. The CTECH2Y100A starts at 5 ft-lb, which reaches light values that a QD3IN200B cannot set.
M10 bolts on vehicle lines and the QYXM14A
Japanese and Korean vehicle plants often use M10 bolts with 14 mm heads on brackets and mounts. A preset QC3P150 at the station, fitted with the Snap-on QYXM14A box end head, gives each operator the same value on every unit. The closed ring also suits flange bolts, since it seats square on the flats. However, check that the head is truly 14 mm, because many M10 parts use 16 or 17 mm.

Questions on the 14 mm Y ring
Does the brochure list an X-shank ring at 14 mm?
No. X rings begin at 17 mm there, so the QYXM14A carries the highest 14 mm limit in that table.
How does 1,400 in-lb convert for the QYXM14A?
It equals about 117 ft-lb, or roughly 158 N·m.
Can a QD3IN200B overload the QYXM14A?
Yes. Its scale climbs to 140 ft-lb, so set a hard cap below 117 ft-lb on the job card.
