Description
Large bolts on machine frames, presses and steel structures often carry a 32 mm hex, and the space above them is rarely generous. The Snap-on QXXM32A box end head puts a 12-point ring on an X-shank torque body. As a result, a team can tighten those bolts with full corner contact and a low stack height.
Snap-on figures for the QXXM32A
| Opening | 32 mm, 12-point box end |
|---|---|
| Shank | X (0.735 in) |
| O.D. | 46 mm |
| Head depth | 19 mm |
| Fastener center to retaining pin | 4.50 in (QXXM series) |
Snap-on’s UK torque brochure lists these values. However, the published torque ratings for the QXXM32A do not agree between sources, so we leave the rating out.
Why a ring suits heavy 32 mm joints
High torque on a big hex punishes an open jaw. For instance, a 32 mm open-end head touches only two flats, so it can spread or round the corners under load. The QXXM32A shares the load across all corners instead. Therefore it suits final torque on frame and flange bolts, where a slip could damage both the bolt and the tool.
Clearance check for the Snap-on QXXM32A box end head
Compare the ring with the open-end option at this size. Snap-on’s 32 mm open-end heads measure 65 mm across and 14 mm deep. The QXXM32A, by contrast, measures 46 mm across but 19 mm deep. So the ring fits a narrow pocket better, while the open jaw slips under a lower lip. Measure both gaps on the machine before you choose.
X bodies and the 4.50 in reach
X-shank bodies in Snap-on’s CAT1500i include the QD3IN350A dual-range body and the QC4P300 preset. The QXXM32A sets the fastener 4.50 in from the pin, the standard X spacing. So the dual-range body needs no adjustment calculation, according to Snap-on. For heavier work on a Z body, the QZXM32A ring covers the same size.
Care for the QXXM32A
Clean the ring and the bolt head before each use. Then check the pin and bore for play, because a loose head tilts on the nut. Also keep the Snap-on QXXM32A box end head with its X body, so the pair goes for calibration together.

QXXM32A FAQ
Will it fit a 32 mm hydraulic fitting?
Yes, if the nut has a 32 mm hex and no tube runs through it. For tube nuts, use a flare nut head instead.
Should I choose the QXXM32A or the QZXM32A?
Choose by the body you own and the torque spec. The Z version suits a Z body and heavier joints.
Can I set 300 ft-lb with it?
Not without confirmation. Snap-on sources list different limits for this head, so ask Lost in HCM before you set a high value.
