Description
The Snap-on IZTRAT9X12 ratchet insert brings a 1/4 in square drive to torque wrenches with a 9 x 12 mm IZO/ISO insert fitting. Snap-on rates it at 25 N·m, the lowest limit among its ratchet inserts. So it suits light fasteners on wrenches that use the 9 x 12 mm system.
Rating and size of the IZTRAT9X12
| Item | Value |
|---|---|
| Square drive | 1/4 in (6 mm) |
| Insert fitting | 9 x 12 mm |
| Width | 37 mm |
| Maximum recommended working torque | 25 N·m (about 18 ft-lb, or 221 in-lb) |
The 9 x 12 mm ratchet family
| Insert | Drive | Width | Max torque |
|---|---|---|---|
| IZTRAT9X12 | 1/4 in | 37 mm | 25 N·m |
| IZFRAT9X12 | 3/8 in | 38 mm | 160 N·m |
| IZSRAT9X12 | 1/2 in | 38 mm | 160 N·m |
So the IZTRAT9X12 is the narrow, low-torque member of the set. Choose it for 1/4 in sockets, and move up to the IZFRAT9X12 once a joint needs more than 25 N·m. The larger 14 x 18 mm inserts need a different wrench fitting altogether.
Pairing the Snap-on IZTRAT9X12 ratchet insert with ControlTech
Snap-on’s ControlTech line includes 9 x 12 mm bodies such as the CTECHAN30A at 1.50-30.00 N·m and the CTECHAN135A at 6.8-135.0 N·m. On the CTECHAN30A, the insert limit sits near the top of the scale. On the CTECHAN135A, however, 25 N·m falls in the lowest part of the range. Therefore, the smaller body usually makes the better partner for this insert. ControlTech wrenches also carry a built-in calibration factor for different head lengths.
Jobs for a 25 N·m ratchet
Small cover screws, sensor brackets and electrical terminals often call for low values. A ratchet insert lets the operator keep the socket on the fastener between swings. In addition, the wrench stays the same while the end changes, so the torque record follows one tool. Never exceed 25 N·m with the IZTRAT9X12, even if the body reads higher.

Insert questions from torque users
How far can I set a wrench with the IZTRAT9X12 fitted?
25 N·m, as Snap-on prints it in CAT1500i.
Will the IZTRAT9X12 fit a 14 x 18 mm wrench?
No. It uses the 9 x 12 mm fitting, so pick a 14 x 18 mm insert such as the IZSRAT14X18 for those bodies.
Which ControlTech body suits the IZTRAT9X12 best?
The CTECHAN30A, since its 30 N·m top end sits just above the insert limit.
