Description
ISO gives M22 hardware a 34 mm hex, yet not every M22 joint is a heavy one. Lock nuts on jack screws, large adapters and coupling nuts often take a moderate value. The Snap-on QYXM34A box end head covers that middle ground. It mounts a closed 34 mm, 12-point ring on the mid-size Y shank, so a 23 in body can do the job.
Ring data for the 34 mm Y head
- Opening: 34 mm, 12-point, closed.
- Shank: Y (0.560 in).
- Outside diameter: 48 mm.
- Head depth: 19 mm.
- Pin to fastener center: 3.00 in (QYXM series).
- Finish: industrial (listing data).
These widths and depths match across the UK brochure and the Lost in HCM listing. So the QYXM34A needs about 24 mm of space from the bolt center to the nearest obstruction.
The Snap-on QYXM34A box end head among the 34 mm rings
Snap-on lists the 34 mm ring for Y, X and Z bodies, with no J version at this size. The brochure gives all three the same 48 mm width and 19 mm depth. However, the reach grows with the shank: 3.00 in on Y, 4.50 in on X and 5.75 in on Z. Pick the QYXM34A when the spec fits a Y body. Move to the X or Z ring only when the value climbs past it.
Y bodies for a 34 mm ring
| Body | Type | Range |
|---|---|---|
| QC3P150 | Preset | 30-150 ft-lb |
| QC3P200 | Preset | 40-200 ft-lb |
| QD3IN200B | Dual scale | 37-140 ft-lb |
| CTECH2Y100A | ControlTech | 5-100 ft-lb |
The QD3IN200B needs no length math, because QD heads share a fixed pin-to-fastener spacing. Snap-on’s sources disagree on the head’s top rating, so we omit it. Lost in HCM confirms the figure for the QYXM34A, and then you cap the body setting there.
Grip and swing with the Snap-on QYXM34A box end head
A closed ring wraps all six corners, so it rarely slips on a large hex. That matters on M22 parts, where one slip can scar a costly casting. In addition, the 12-point layout lets the Snap-on QYXM34A box end head seat every 30 degrees. So you can still find a handle angle when a pipe or guard blocks the swing. Before the pull, seat the ring fully and keep the body square to the bolt axis.

What buyers ask about the 34 mm Y ring
Is there a J-shank 34 mm ring?
No. Snap-on’s metric J rings stop at 27 mm, so the QYXM34A is the lightest 34 mm option.
How far from the pin does the bolt sit?
3.00 in, the spacing Snap-on prints for every QYXM ring.
Where do I get the head’s rating?
From Lost in HCM. The brochure and the listing print different values, so the team confirms one with your quote.
