Snap-on IZ30OE14X18 Torque Insert, 30 mm Open End for 14 x 18 mm IZO Bodies

Description

M20 is one of the sizes where ISO 4032 and DIN 934 agree on the hex: both give the nut 30 mm across flats. The Snap-on IZ30OE14X18 torque insert fits that hex with an open end on a 14 x 18 mm IZO/ISO fitting. Because the jaw slides on from the side, it reaches nuts that sit on a stud or around a pipe.

Where M20 and 30 mm tube nuts need an open jaw

• Lock nuts on M20 jack screws and adjusters, where the screw blocks a ring.
• S16 cutting-ring fittings to ISO 8434-1, whose nuts commonly measure 30 mm.
• M20 nuts on long studs at pump bases and machine frames.

In each case, the Snap-on IZ30OE14X18 torque insert goes on without stripping parts away. Still, measure the flats first, since older drawings and other standards can differ.

The CTECHBN340A band for the Snap-on IZ30OE14X18 torque insert

CAT1500i lists one 14 x 18 mm ControlTech body, the CTECHBN340A. It covers 17.0 to 340.0 N·m and measures 607 mm without a head. Snap-on states that its wrenches hold accuracy from 20 to 100% of full scale. So the useful band on this body runs from 68 to 340 N·m. Since CAT1500i prints no rating for IZO inserts, the body range sets the ceiling.

Swing room and grip with the IZ30OE14X18

A 607 mm body needs a clear arc behind the nut, so check the space before you plan the job. In addition, an open end bears on two flats, while a ring bears on all six. Therefore seat the IZ30OE14X18 fully and square, and pull slowly from the handle grip. Select the stored head-length factor on the ControlTech body as well, so the reading matches the jaw.

IZ30IR14X18 ring versus the IZ30OE14X18 jaw

Snap-on also makes the IZ30IR14X18, a closed 30 mm insert ring on the same fitting. Choose that ring when the nut is open from above, because it wraps the whole hex. Choose the Snap-on IZ30OE14X18 torque insert when a stud, pipe or screw passes through the nut. In CAT1500i, the IZ27OE14X18 and IZ32OE14X18 sit either side of it. No 9 x 12 open end reaches 30 mm, since that range stops at 19 mm.

IZ30OE14X18 checks before you order

Which bolt size takes a 30 mm nut?

M20, in both ISO 4032 and DIN 934. Measure anyway, because heavy structural nuts for M20 run larger.

Does a CTECHAN135A body accept the IZ30OE14X18?

No. That body uses the 9 x 12 mm fitting, while this insert needs a 14 x 18 mm receiver.

What is the lowest value worth setting with this insert?

On the CTECHBN340A, about 68 N·m, the bottom of its 20 to 100% band.
