Snap-on IZ19IR14X18 Insert Ring, 19 mm Closed Ring, 14 x 18 mm IZO Fitting

Description

Two Snap-on insert rings fit a 19 mm hex. One plugs into the compact 9 x 12 mm IZO fitting. The other, the Snap-on IZ19IR14X18 insert ring, plugs into the larger 14 x 18 mm fitting. So the joint torque decides between them, because each fitting matches a different ControlTech body.

Torque decides the 19 mm ring

A joint above 135 N·m rules out the small fitting at once. That leaves the IZ19IR14X18 on the BN340A. Lighter joints, by contrast, may read better on the smaller body. Snap-on certifies its wrenches from 20 to 100% of full scale, and on the BN340A that window opens at 68 N·m.

The Snap-on IZ19IR14X18 insert ring among its neighbors

On the 14 x 18 mm fitting, Snap-on lists rings at 13, 14, 15, 17, 19, 22, 24, 27, 30, 32 and 36 mm. The 19 mm ring therefore sits between the 17 and 22 mm parts, with no 18 or 21 mm step. In addition, the IZ19OE14X18 gives the same fitting a 19 mm open end. So a single BN340A can serve a station with mixed hex sizes, and the operator swaps inserts as the job changes.

Frames, covers and the 19 mm hex

Heavy equipment builders torque many M12 joints on frames, brackets and gearbox covers. Older DIN 931 and DIN 933 bolts at M12 carry a 19 mm hex, while ISO 4017 trims that size to 18 mm. Check the bolt standard on the drawing before you assign the IZ19IR14X18. When it reads DIN, the closed ring wraps the whole hex and spreads the load.

Setting up the Snap-on IZ19IR14X18 insert ring

Push the ring into the 14 x 18 mm receiver until the lock engages, then tug it to confirm it holds. Next, pick the matching head entry, since ControlTech bodies store a calibration factor for different head lengths. Keep the wrench square to the bolt through the pull. Also, never crack a seized bolt with it, as Snap-on warns.

Price and supply of the 19 mm IZ19IR14X18

SMK Vietnam lists the Snap-on IZ19IR14X18 insert ring for its partner, and Lost in HCM supplies it and quotes it. Share the body model, the joint torque and the bolt standard. Lost in HCM can then quote the IZ19IR14X18 for your station. More inserts sit under torque wrench heads and adaptors, or you can contact SMK Vietnam with questions.

IZ19IR14X18 questions from heavy assembly

Which body suits a 200 N·m joint with this ring?

The CTECHBN340A. Its 17.0-340.0 N·m span covers that value, and it takes the 14 x 18 mm fitting of the IZ19IR14X18.

What if pipework blocks the top of the bolt?

Use the IZ19OE14X18 open end insert instead, which reaches the hex from the side.

Does Snap-on rate the IZ19IR14X18 itself?

CAT1500i prints no torque figure for IZO inserts, so the rated capacity of the body sets the ceiling.
