Description
The Snap-on QJBOERM22A box end head puts a 22 mm 12-point ratcheting ring on a J-shank interchangeable torque wrench. It is the second-largest metric size in the J column, just below the 24 mm head. Snap-on offers no Y version at 22 mm, so this head is the only 22 mm choice in the range.
Size data for the 22 mm QJBOERM22A
- Size: 22 mm, 12-point, ratcheting box end.
- Shank: J (0.425 in).
- O.D.: 41.7 mm.
- Head depth: 14.5 mm.
- Pin to fastener center: 2.50 in, per the QJBOER series line.
The 22 mm head shares its 41.7 mm O.D. with the 19 mm head, yet it runs deeper at 14.5 mm against 12.9 mm. By contrast, the 24 mm QJBOERM24A steps up to 46.5 mm and 15.5 mm.
A big ring on a light shank
J shanks serve the lighter bodies in Snap-on’s range, for instance the QC2I75 at 5-75 ft-lb and the QD2IN100A at 20-100 N·m. A 22 mm nut often needs more torque than small fasteners. So check that your spec falls inside the body range. Also note that CAT1500i prints no maximum working torque for the ratcheting box end heads. Therefore, ask Lost in HCM to confirm the QJBOERM22A limit before you set a high value.
Fasteners that take a 22 mm ring
Under DIN 934, an M14 hex nut measures 22 mm across flats, while the ISO 4032 M14 nut measures 21 mm. So check your drawings, since many machines mix both standards. In addition, 22 mm hex fittings appear on hoses, sensors and pipe unions. The 12-point ring of the QJBOERM22A engages every 30 degrees, which helps when the swing is short.
Using the Snap-on QJBOERM22A box end head
Seat the ring fully over the nut and keep the wrench square to it. Next, draw the handle at an even pace until it clicks. Snap-on warns against using its torque bodies to break fasteners loose, so free a seized nut with a plain wrench first. For the dual-range bodies, Snap-on says plug-and-play heads share one pin-to-fastener size, so no adjustment math applies. With other bodies, check the manual.

22 mm box end head questions
Is there a Y-shank 22 mm box end head?
No. CAT1500i lists Y versions only at 16, 18 and 24 mm.
What is the head depth of the QJBOERM22A?
14.5 mm, with a 41.7 mm O.D., according to Snap-on.
What torque limit applies to the QJBOERM22A?
CAT1500i prints none for this family, so ask Lost in HCM to confirm it in the quote.
