Description
Snap-on makes a 14 mm insert ring twice, once for each IZO fitting size. The Snap-on IZ14IR14X18 insert ring is the version for the larger 14 x 18 mm receiver. So the real question is not the nut size but the wrench you already own.
Two 14 mm rings, two receivers
| IZ14IR9X12 | IZ14IR14X18 | |
|---|---|---|
| Ring size | 14 mm | 14 mm |
| Fitting | 9 x 12 mm | 14 x 18 mm |
| Example ControlTech body | CTECHAN30A (1.5-30 N·m) or CTECHAN135A (6.8-135 N·m) | CTECHBN340A (17-340 N·m) |
The fitting must match the receiver exactly, so a 9 x 12 insert will not lock into a 14 x 18 body. Check the size marked on your wrench or its manual, then order the matching ring.
When the IZ14IR14X18 makes sense
Some lines tighten 14 mm bolts and much larger nuts in one sequence. In that case, one 14 x 18 body with several inserts saves a second wrench. For example, an operator can swap from this ring to a 30 mm ring on the same body. Also, a plant that owns only the CTECHBN340A needs the 14 x 18 ring to reach this size at all.
Check the low end first
The CTECHBN340A starts reading at 17 N·m. Therefore, the Snap-on IZ14IR14X18 insert ring suits joints above that point. Below it, a 9 x 12 body with the IZ14IR9X12 fits better. Small fasteners on covers and light brackets can fall near that figure. So compare your spec with the body range before you choose the fitting.
The size itself turns up often in Japanese-built equipment, because JIS small-series M10 bolts use a 14 mm hex. Still, confirm the hardware on your own drawing.
Neighbouring sizes on the 14 x 18 fitting
The 14 x 18 rings run 13, 14, 15, 17, 19, 22, 24, 27, 30, 32 and 36 mm. So the IZ14IR14X18 sits between the 13 mm and 15 mm rings. In addition, Snap-on offers a 14 mm open-end insert, the IZ14OE14X18, for nuts you can only reach from the side.
Snap-on IZ14IR14X18 insert ring: daily use
Push the shank in until the lock engages, then tug it to confirm. Next, select the matching head-length factor on the CTECHBN340A, since the body stores one for different lengths. Pull smoothly through the signal and stop. Finally, never use the ring to free a seized bolt, and keep the wrench on its recalibration plan.

Buyer questions on the IZ14IR14X18
How do I tell which IZO fitting my wrench takes?
Check the receiver size on the body or in its manual. ControlTech IZO models list either 9 x 12 mm or 14 x 18 mm.
Is there a 14 mm open-end insert for this fitting?
Yes. Snap-on lists the IZ14OE14X18 on the same 14 x 18 mm fitting.
Can I torque below 17 N·m with the IZ14IR14X18?
Not on the CTECHBN340A, whose range starts at 17 N·m. Use a 9 x 12 body and the IZ14IR9X12 instead.
