Description
A 36 mm nut is about as big as the IZO insert system goes. The Snap-on IZ36OE14X18 torque insert covers that size with an OE head on a 14 x 18 mm fitting. So it turns a 14 x 18 interchangeable wrench into a tool for large metric hex work, such as M24 joints with ISO-size nuts.
Top of the IZO OE range
Snap-on’s 14 x 18 OE inserts run 13, 14, 15, 17, 18, 19, 22, 24, 27, 30, 32 and 36 mm. The IZ36OE14X18 closes the list. Meanwhile, the smaller 9 x 12 OE range stops at 19 mm, so no 9 x 12 wrench can take a 36 mm insert. If your nut measures 32 mm instead, the IZ32OE14X18 is the next size down.
Snap-on also lists a 36 mm insert ring, the IZ36IR14X18, on the same fitting. A ring wraps the whole nut, while the OE style can reach nuts a ring cannot pass over. Therefore, decide on the head style once you know how the joint is built.
The wrench sets the limit for the Snap-on IZ36OE14X18 torque insert
Snap-on prints no torque rating for its OE inserts. In practice, the 14 x 18 wrench decides how far you can go. The ControlTech CTECHBN340A, for example, reads 17 to 340 N·m. Large M24 joints often call for more than that, especially with high-grade bolts. So compare your drawing value with 340 N·m before you order. If the spec runs higher, you need a heavier tightening system rather than this insert.
ControlTech wrenches also hold a calibration factor for each head length. Because a 36 mm head sits farther out than a small one, set that factor for the IZ36OE14X18 each time you fit it.
Jobs that suit a 36 mm OE head
- Anchor and base bolts on pumps, gearboxes and motor frames.
- Large flange and structural nuts in steel fabrication.
- Heavy-equipment and press assembly where the spec stays within the wrench range.
For each of these, the Snap-on IZ36OE14X18 torque insert adds a 36 mm grip to a wrench you may already own.
Handling a large insert
A big head adds leverage to any side load. Thus, keep the wrench square to the nut and pull smoothly through the click. Also clean the 14 x 18 fitting before each swap, since grit can stop it from seating. Never use the insert to break a nut loose. Finally, book the wrench for periodic recalibration, which Snap-on calls necessary for accuracy.

IZ36OE14X18 questions
Is there a 36 mm insert for 9 x 12 wrenches?
No. The 9 x 12 OE range ends at 19 mm, so 36 mm comes only on the 14 x 18 fitting.
How much torque can I apply with it?
Snap-on does not print an insert rating. Stay within your wrench range, which tops out at 340 N·m on the CTECHBN340A.
What is the next size down?
The IZ32OE14X18 covers 32 mm nuts on the same fitting.
