Description
Some torque wrenches take rectangular insert tools rather than round shanks. The Snap-on IZ18OE14X18 torque insert follows that system. It carries an 18 mm OE head on a 14 x 18 mm fitting. So it slides into any matching IZO/ISO receiver.
What the IZ18OE14X18 is
Snap-on’s catalog lists this part in its IZO Torque Insert Heads table as an “18 mm OE insert 14 x 18”. The first figure gives the fastener size. Meanwhile, the second pair gives the fitting size in millimeters. That fitting decides which wrench bodies accept the insert.
Wrenches that take the Snap-on IZ18OE14X18 torque insert
On SMK Vietnam, the CTECHBN340A ControlTech wrench uses a 14 x 18 mm IZO/ISO receiver. Snap-on lists it from 17 to 340 N·m. In contrast, the CTECHAN30A, CTECHAN135A and CTECHANM30 use a 9 x 12 mm fitting. They need 9 x 12 inserts instead. Snap-on also notes a built-in calibration factor for head length on ControlTech wrenches. So follow the wrench manual each time you fit the Snap-on IZ18OE14X18 torque insert or another insert.
Building an IZO insert kit around the IZ18OE14X18
Snap-on offers the 14 x 18 range in several forms, such as:
- OE inserts from 13 to 36 mm, including this 18 mm size.
- Insert rings from 13 to 36 mm.
- Square drive ratchet inserts, for instance the IZSRAT14X18 at 1/2 in drive.
- A welding insert, the IZWI14X18, for custom tools.
Start with the 18 mm insert if most of your joints use that hex size. Then add the sizes your drawings call for next.
IZ18OE14X18 torque limits and care
Snap-on does not print a separate working torque for its OE inserts. Before you set a high value, therefore, ask Lost in HCM to confirm the limit. Also follow Snap-on’s torque warnings: do not exceed rated capacity, and do not use the tool to break fasteners loose. Finally, keep the insert fitting clean, because grit can stop it from seating fully.

IZ18OE14X18 FAQ
Will it fit a 9 x 12 mm wrench?
No. The IZ18OE14X18 has a 14 x 18 mm fitting, so a 9 x 12 receiver needs a 9 x 12 insert.
Does it fit QD or QC click bodies?
No. Those bodies use round J, Y, X or Z shanks rather than an IZO fitting.
What fastener size does it fit?
Snap-on describes it as an 18 mm OE insert.
