Snap-on QYXM19A Box End Head, 19 mm 12-Point Ring, Y Shank (0.560″)

Description

Already own a Y-shank click wrench? Then the Snap-on QYXM19A box end head is the 19 mm ring that locks straight into it. In short, you add a size without buying a new body. It wraps a closed 12-point ring around DIN M12 hardware and other 19 mm hex parts. Also, the Y shank carries a good deal more load than the light J version of this size.

One size, three shanks

Snap-on’s UK brochure lists 19 mm rings for J, Y and X bodies. All three share the same 28 mm O.D. and 12 mm depth, so the ring itself looks alike. The difference lies in the shank and in how far the ring sits from the locking pin.

Both the brochure and the partner listing rate the Y ring at well over twice the J ring. Still, their exact figures for the QYXM19A differ. Therefore Lost in HCM confirms the limit with the quote.

Which Y wrench suits the Snap-on QYXM19A box end head

A QD3IN200B gives a dual scale of 40-200 N·m, or 37-140 ft-lb, on a 23 in tube. For one fixed value per station, the QC3P150 and QC3P200 presets cover 30-150 and 40-200 ft-lb. Then there is the CTECH2Y100A, an electronic body that reads from 5 to 100 ft-lb. It also stores a factor for head length, which suits the 3.00 in reach of this ring.

Habits that protect a 19 mm Y ring

First, wipe the shank and the socket before you push the ring home. Next, check that the locking pin clicks out fully. Snap-on also warns against using these heads to break fasteners loose. So crack a seized nut with a breaker bar, then use the Snap-on QYXM19A box end head for the final value. Finally, store the ring dry, because grit in the 12 points can mark the bolt corners.

Choosing the QYXM19A

Is the QYXM19A rated higher than the J ring of the same size?

Yes. Both sources put it at well over twice the QJXM19A, although their exact numbers differ. Lost in HCM confirms the limit.

Does the 3.00 in reach change my wrench setting?

Head length affects the torque at the nut. The CTECH2Y100A stores a factor for it, so for a click body ask Lost in HCM how Snap-on wants it set.

Can the QYXM19A loosen a seized nut?

No. Snap-on warns against breaking fasteners loose with these tools. Use a breaker bar first, then torque with the ring.
