Description
Twenty-six is an odd hex on metric machines. ISO bolts jump from 24 mm on M16 to 27 mm on M18, so a 26 mm hex usually marks a fitting, a union or a special lock nut. The Snap-on QYOM26A open end head fits that size to a Y-shank torque body, the mid-weight option between the J and X shanks.
How big is the QYOM26A?
- Jaw size: 26 mm.
- Shank: Y (0.560 in).
- Pin to fastener center: 3.00 in, as on every QYOM head.
- O.D.: 53 mm.
- Head depth: 11 mm.
CAT1500i and the UK brochure agree on those dimensions. They do not agree on the torque limit, however. So the rating stays off this page until Lost in HCM confirms it for your order.
Why the Y shank suits a 26 mm part
The J shank keeps tools small, while the X shank handles heavier work. The Y shank sits between them, with a 3.00 in pin spacing. For a 26 mm fitting with a medium spec, the QYOM26A on a Y body often gives the best balance. Y bodies in CAT1500i run 23 in long, yet they carry far more than a J tool. Also, CAT1500i lists 26 mm heads in J, Y, X and Z, so you can still change shank later.
Three Y bodies that take the Snap-on QYOM26A open end head
CAT1500i offers three Y bodies. First, the QC3P150 presets from 30 to 150 ft-lb. Next, the QC3P200 presets from 40 to 200 ft-lb. Meanwhile, the QD3IN200B adjusts from 40 to 200 N·m, about 37 to 140 ft-lb, and Snap-on supplies QD bodies with a calibration certificate. Because the head rating is still open here, set any body only after Lost in HCM gives you that value.
Jobs that call for a 26 mm open jaw
Hydraulic power units and coolant systems often use large fittings with odd hex sizes. For example, a 26 mm adapter may sit between two hoses, so a socket cannot reach it. The Snap-on QYOM26A open end head slides on from the side, and the click marks the target. In addition, its 11 mm depth lets it bite on a short hex land.
Neighbors: 24 mm, 27 mm and other shanks
If the part measures 24 mm, it is likely an M16 hex, and the QYOM24A fits it. At 27 mm, the M18 size, CAT1500i lists the QYOM27A. Also, the X-shank QXOM26A shares this opening, which helps when a station already runs X bodies. Check the hex with a caliper, because paint and wear can mislead you.

Before you buy a QYOM26A
Which bolt takes a 26 mm wrench?
No standard ISO hex bolt does. A 26 mm hex usually belongs to a fitting, union or special nut.
Why does this page skip the QYOM26A torque rating?
Snap-on’s catalog and its UK brochure print different limits. Lost in HCM confirms the right one with your quote.
How much clearance does the QYOM26A need?
It measures 53 mm across the head and 11 mm deep, so plan for that space around the hex.
