Description
A 15 mm open end is small for a 14 x 18 mm receiver, and that is the point of the Snap-on IZ15OE14X18 torque insert. It lets a large ControlTech body work 15 mm flats without a second wrench. CAT1500i also lists the same jaw for 9 x 12 bodies, as the IZ15OE9X12. So the choice comes down to the body and the joint value.
Two 15 mm jaws, two bodies
| Insert | Fitting | ControlTech body | Certified band |
|---|---|---|---|
| IZ15OE9X12 | 9 x 12 mm | CTECHAN135A | 27-135 N·m |
| IZ15OE14X18 | 14 x 18 mm | CTECHBN340A | 68-340 N·m |
In short, the IZ15OE14X18 makes sense when the joint sits above the 9 x 12 band. It also helps when a station runs one CTECHBN340A for many sizes.
A shared-body station for the Snap-on IZ15OE14X18 torque insert
Picture an assembly cell with one CTECHBN340A and a tray of 14 x 18 inserts. Most joints on the frame use large nuts, but one bracket uses 15 mm flats. Instead of a second wrench, the operator clips on the IZ15OE14X18 and selects its head factor. Then the same body and its stored presets cover the whole sequence. First, though, confirm that the 15 mm joint sits inside the 68 to 340 N·m band.
What carries 15 mm flats?
Standard metric nuts skip this width. For example, ISO 4032 gives M10 nuts 16 mm, and DIN 934 gives them 17 mm. So 15 mm flats usually belong to special parts, such as some tube fittings, valve bodies or custom nuts. Measure the part first, then order the Snap-on IZ15OE14X18 torque insert.
Ring or open end for the Snap-on IZ15OE14X18 torque insert
Snap-on also lists the IZ15IR14X18, a closed 15 mm ring on the same fitting. Choose the ring when you can drop it over the nut, because it grips all six flats. Keep the IZ15OE14X18 for nuts on tubes, rods or studs. Either way, use a plain spanner to break a nut loose, since Snap-on rules out that use.

Choosing the IZ15OE14X18: FAQ
Will my CTECHAN135A take this insert?
No. The CTECHAN135A has a 9 x 12 mm receiver, so order the IZ15OE9X12 for that body.
Which open ends sit either side of 15 mm on 14 x 18?
The IZ14OE14X18 at 14 mm and the IZ17OE14X18 at 17 mm. CAT1500i lists no 16 mm open end on this fitting.
Is a light 15 mm joint a good match?
Not on this body. Below about 68 N·m, the 9 x 12 version on a CTECHAN135A reads within its band.
