Description
The 9 x 12 mm open-end range in CAT1500i starts at 7 mm and stops at 19 mm. The Snap-on IZ19OE9X12 torque insert is that top size. It lets a mid-size ControlTech body work 19 mm nuts from the side. So one 9 x 12 wrench can cover a station’s small and medium hardware.
Which 9 x 12 body suits the Snap-on IZ19OE9X12 torque insert?
| Body | Range | Certified band (20-100%) |
|---|---|---|
| CTECHAN30A | 1.50-30.00 N·m | 6-30 N·m |
| CTECHANM30 | 1.5-30 N·m | 6-30 N·m |
| CTECHAN135A | 6.8-135.0 N·m | 27-135 N·m |
The 30 N·m bodies suit small fasteners, so the CTECHAN135A is the natural partner for a nut this size. Check your joint value against its 27 to 135 N·m band first.
IZ19OE9X12 or IZ19OE14X18?
Snap-on makes the same 19 mm jaw on the 14 x 18 mm fitting, as the IZ19OE14X18. That twin needs the CTECHBN340A, whose band starts near 68 N·m. So the joint value decides. Up to 135 N·m, the IZ19OE9X12 on a CTECHAN135A reads within band. Above that, move to the 14 x 18 pair.
M12 hardware and the Snap-on IZ19OE9X12 torque insert
DIN 934 gives M12 nuts 19 mm across flats, while ISO 4032 uses 18 mm. Therefore check which standard your drawing calls up. On the shop floor, a 19 mm open end often meets lock nuts on M12 adjusting screws, such as conveyor take-ups. There, the screw runs through the nut, so a ring cannot go on.
Handling the IZ19OE9X12
Seat the jaw fully before you pull. An open end holds only two flats, so a shallow grip can slip and round the corners. Also select the matching head-length factor on the ControlTech body. Finally, never use the insert to break a nut loose, as Snap-on warns.

IZ19OE9X12 fit questions
Is there a 20 mm or larger open end for 9 x 12?
No. The 9 x 12 open-end range in CAT1500i ends at 19 mm. Larger jaws use the 14 x 18 mm fitting.
Which receiver size does the IZ19OE9X12 need?
A 9 x 12 mm IZO/ISO receiver, as on the CTECHAN135A. The 14 x 18 mm CTECHBN340A will not accept it.
Is there a closed 19 mm ring for 9 x 12?
Yes, the IZ19IR9X12 insert ring. Use it when the nut is clear from above.
