Description
Anchor rods, leveling screws and long studs often carry M18 nuts that a ring cannot reach from above. The Snap-on IZ27OE14X18 torque insert takes those nuts from the side. Its 27 mm open end mounts on the 14 x 18 mm IZO/ISO fitting. In CAT1500i, that receiver belongs to the CTECHBN340A ControlTech body.
27 mm and its neighbors in the IZO range
| Part | Type | Fitting |
|---|---|---|
| IZ24OE14X18 | 24 mm open end | 14 x 18 mm |
| IZ27OE14X18 | 27 mm open end | 14 x 18 mm |
| IZ27IR14X18 | 27 mm insert ring | 14 x 18 mm |
| IZ30OE14X18 | 30 mm open end | 14 x 18 mm |
No 9 x 12 part reaches 27 mm, because that open-end range ends at 19 mm. So any 27 mm job on a ControlTech IZO body calls for the 14 x 18 receiver.
Matching the Snap-on IZ27OE14X18 torque insert to M18 hardware
ISO 4032 and DIN 934 both give M18 nuts 27 mm across flats. That makes the IZ27OE14X18 a fit for most metric M18 hardware. Cutting-ring tube fittings can use 27 mm nuts as well, for example on some L15 and S14 lines. Still, measure each nut, since special and heavy nuts vary.
Setting the CTECHBN340A for the IZ27OE14X18
The CTECHBN340A reads 17.0 to 340.0 N·m. Snap-on certifies its wrenches from 20 to 100% of full scale, so the useful band starts near 68 N·m. No published limit exists for IZO inserts in CAT1500i, which leaves the body scale as the practical cap. Before the first pull, select the stored head-length factor for this insert. Then the display matches the torque at the jaw.
Keeping the open jaw square
An open end bears on two flats only. So it needs full depth on the nut and a square approach. Push the IZ27OE14X18 on until the flats bottom in the jaw, then pull slowly at the grip. In addition, break old nuts loose with a plain spanner, as Snap-on advises. Inspect the jaw faces from time to time, because a spread jaw marks the corners.

IZ27OE14X18 before you buy
What metric thread pairs with a 27 mm hex?
M18, in both ISO 4032 and DIN 934 nuts.
When is the IZ27IR14X18 ring the better buy?
When the nut is open from above. A closed ring bears on all six flats rather than two.
Can I torque a 40 N·m joint with this insert?
Not within band. The CTECHBN340A band starts near 68 N·m, so a lighter 27 mm joint needs a different tool.
