Description
Twenty-six millimeters falls between the common 24 mm and 27 mm hex sizes, yet some hydraulic adapters and machine fasteners use it. The Snap-on QXOM26A open end head gives an X-shank torque body that exact jaw. As a result, a team can torque a 26 mm nut without forcing a 27 mm tool onto it.
Published dimensions of the QXOM26A
- Opening: 26 mm, open end.
- Shank: X (0.735 in).
- O.D.: 53 mm.
- Head depth: 11 mm.
- Fastener center to retaining pin: 4.50 in, the QXOM series value.
Snap-on’s two main sources disagree on the maximum torque for the QXOM26A. Therefore we omit it, and Lost in HCM confirms the limit with your quote.
The 4.50 in reach of the QXOM26A
X heads place the fastener 4.50 in from the retaining pin, compared with 3.00 in for Y heads. That longer spacing matches Snap-on’s X bodies. For instance, the QD3IN350A dual-range body reads 70 to 350 N·m, or 59 to 251 ft-lb. The QC4P300 preset covers 60 to 300 ft-lb instead. Snap-on says its QD bodies need no adjustment calculation with heads sized this way. However, other brands of body may need one, so follow that maker’s manual.
When the Snap-on QXOM26A open end head is the right pick
Pick the X head when two things are true. First, your station already runs X bodies. Second, the 26 mm joint sits above what a lighter shank handles. Otherwise, the QYOM26A on a Y body is lighter and shorter. For the heaviest 26 mm joints, the dual-pin QZOM26ADP fits a Z body.
Side access around 26 mm fittings
At 53 mm across, the QXOM26A needs a clear swing beside the nut. Meanwhile, its 11 mm depth slips under brackets and clamps. So it suits tube nuts and adapters where a pipe passes through the joint. However, a long X body needs space for the pull, so plan the arc first.
Keeping a QXOM26A accurate in use
Clean the jaw and the nut before each pull. Then make sure the shank seats fully and the pin locks. Also never use the head to break a fastener loose, because Snap-on warns against that.

QXOM26A questions from maintenance buyers
Will a 27 mm head do on a 26 mm nut?
No. The loose fit can round the corners, so use the exact 26 mm jaw.
Which X body suits the QXOM26A?
Snap-on’s QD3IN350A and QC4P300 both take X heads. Pick by your torque value and whether you need one fixed setting.
Does Snap-on publish one torque limit for the QXOM26A?
Not consistently. Its catalog and brochure list different values, so Lost in HCM confirms the figure.
