Description
An M30 bolt carries a 46 mm hex under ISO, and that size sits on heavy machinery all over a factory. For example, machine anchor bolts, large compressor feet and thick flange pairs often use it. The Snap-on QZOM46A open end head gives a Z-shank torque body a 46 mm jaw for those joints, so you can reach a nut beside a column or under a guard.
QZOM46A facts we could check
- Opening: 46 mm, open end.
- Shank: Z (0.990 in).
- Fastener center to retaining pin: 5.75 in (QZOM series).
- Part number: no DP suffix.
Snap-on’s CAT1500i table at 46 mm shows the QXOM46A and the dual-pin QZOM46ADP, but not this part. So we do not print a rating, width or depth for the QZOM46A. Instead, Lost in HCM confirms them with your quote.
QZOM46A, QZOM46ADP or QXOM46A?
| Part | Shank | Rating |
|---|---|---|
| QXOM46A | X | 240 ft-lb (CAT1500i) |
| QZOM46ADP | Z, dual pins | 480 ft-lb (CAT1500i) |
| QZOM46A | Z, no DP suffix | Confirm with Lost in HCM |
If your station runs X bodies, the QXOM46A avoids a new handle. If you own a dual-pin Z body, the QZOM46ADP has a published rating. The Snap-on QZOM46A open end head suits buyers who need this exact part number, for example to match an existing kit.
M30 work with the Snap-on QZOM46A open end head
M30 joints often carry high torque specs, so check yours against the head limit first. Then square the jaw fully on two flats, because the whole load passes through them. Pull smoothly, and stop at the click. Also keep helpers clear of the swing, since a Z body is long.
Which Z body takes the QZOM46A?
CAT1500i lists the QD4IN800A as its Z dual-range body, at 129 to 572 ft-lb. However, that table carries a note for dual-pin heads only. Because the QZOM46A has no DP suffix, it may not suit that body. Tell Lost in HCM which Z body you use, and they can confirm the fit before you order.
Neighbors at 41 and 50 mm
One step down from the QZOM46A, CAT1500i lists 41 mm heads in Y, X and Z. One step up, it lists 50 mm heads in Y and Z. So measure the hex before you order, because heavy hex and flange nuts may not match the standard M30 size.
QZOM46A storage and checks
Inspect the jaw faces for spread after each heavy job. Then clean the shank and the pin bore. Finally, hang the head on a labeled rack beside its body, so it stays dry and easy to find.

Questions about the QZOM46A
Does the QZOM46A fit M30 nuts?
Yes, if the nut has the standard 46 mm hex. Measure flange and heavy nuts first.
Why buy the QZOM46A instead of the ADP version?
Mostly to match a kit or body that uses this part number. Otherwise, the QZOM46ADP has a published rating.
Where does the QZOM46A rating come from?
Lost in HCM confirms it with your quote, because the CAT1500i table does not list this exact part.
