Description
A wide hex does not always come with a high torque value. Brass unions, aluminum plugs and threaded sensor bodies often carry a 26 mm hex but only a modest spec. The Snap-on QJXM26A box end head serves that mix. It pairs a closed 26 mm, 12-point ring with the light J shank, so a small click body can finish the joint.
Snap-on QJXM26A box end head: printed sizes
| Opening | 26 mm, closed 12-point ring |
|---|---|
| Shank | J (0.425 in) |
| Outside diameter | 38 mm |
| Head depth | 16 mm |
| Fastener center to retaining pin | 2.50 in (QJXM series) |
The UK torque brochure and the partner listing agree on every figure above. Half of the 38 mm width is 19 mm, so the QJXM26A needs that much room from the hex center to the nearest wall.
A large ring on a light shank
Snap-on cuts the 26 mm ring for all four shanks. The brochure lists the QJXM26A, QYXM26A, QXXM26A and QZXM26A in one row, with one shared width and depth. So clearance never decides between them. Instead, the torque value and the body you already own make the choice. For example, the J version keeps the whole tool short and light, which helps on a crowded panel or a test bench.
J bodies that carry the Snap-on QJXM26A box end head
Every J click body in Snap-on’s CAT1500i catalog takes this ring directly. The largest of them stop at about 75 ft-lb, so a J ring stays in light work by design.
- QC2I75 adjustable, 5-75 ft-lb, for mixed values across a shift.
- QC2P75 preset, 5-75 ft-lb, locked to one value on a line.
- QD2IN100A dual scale, 16.6-71.9 ft-lb (20-100 N·m), with no length math at 2.50 in.
Snap-on’s brochure and the partner listing disagree on the maximum rating for this ring. Therefore we leave the number out, and Lost in HCM confirms it with your quote. Then set the body at or below that confirmed limit.
Parts that carry a 26 mm hex
ISO bolt tables skip 26 mm, because M16 uses 24 mm and M18 uses 27 mm. As a result, a 26 mm hex usually belongs to a special part rather than a standard bolt. Typical examples include pipe unions, hydraulic plugs, gland nuts and threaded sensor bodies. Many of these parts are soft or thin-walled, so a light J setting suits them. Still, measure the flats before you order the Snap-on QJXM26A box end head, since a 27 mm part looks almost the same.

Before you order the 26 mm J ring
Is the QJXM26A right for M18 hardware?
No. ISO M18 hardware uses a 27 mm hex, so a 27 mm ring such as the QJXM27A is the right match.
How much side room does the 26 mm J ring need?
About 19 mm from the hex center, which is half of its 38 mm outside diameter.
Does the QJXM26A suit a heavy steel joint?
Usually not. J bodies top out near 75 ft-lb, so firm specs belong on the Y, X or Z ring.
