Snap-on IZ13IR9X12 Insert Ring, 13 mm Closed Ring for 9 x 12 mm IZO Torque Wrenches

Description

Panel builders and electrical teams tighten a lot of M8 hardware on bus bars, earth studs and cable lugs. An ISO 4017 M8 bolt has a 13 mm hex. The Snap-on IZ13IR9X12 insert ring fits that hex with a closed ring on the 9 x 12 mm IZO fitting. As a result, a compact electronic body can torque and record each joint.

Two 9 x 12 bodies for the Snap-on IZ13IR9X12 insert ring

Snap-on certifies its wrenches from 20 to 100% of full scale. On the AN30A, that window runs from 6 to 30 N·m. For the AN135A, it starts at 27 N·m. So match the body to the joint value first, then fit the ring. Because both bodies share the fitting, one IZ13IR9X12 can move between them.

Closed ring or open end at 13 mm

A closed ring wraps the whole hex, so it suits bolt heads and nuts with clear space above. However, a nut on a fitting or a threaded tube needs a side entry. For that case, Snap-on offers the IZ13OE9X12 open end on the same fitting as the IZ13IR9X12. The larger 14 x 18 mm fitting also carries 13 mm parts, yet those need a heavier body such as the CTECHBN340A.

Where the IZ13IR9X12 sits among 9 x 12 rings

Snap-on lists 9 x 12 mm rings at 10, 11, 12, 13, 14, 15, 17 and 19 mm. So the 13 mm ring sits in the middle of a compact set. Note the gaps at 16 and 18 mm. Only open end inserts, such as the IZ16OE9X12 and IZ18OE9X12, fill them on this fitting.

Daily care of the IZ13IR9X12

Wipe the ring and the receiver before each shift, because grit can stop the lock from seating. Then check the ring bore for spread or cracks. Store the insert in its own slot rather than loose in a drawer. Finally, follow Snap-on’s advice that periodic recalibration keeps the body accurate.

IZ13IR9X12 questions from the line

Which wrench reads a 10 N·m joint best with this ring?

The CTECHAN30A, because 10 N·m sits inside its 20-100% window of 6 to 30 N·m. The IZ13IR9X12 fits it directly.

Can one ring serve both the AN30A and the AN135A?

Yes. Both bodies take the 9 x 12 mm fitting, so the ring moves between them.

Is there a 16 mm ring for this fitting?

No. Snap-on’s 9 x 12 rings skip 16 mm, though the IZ16OE9X12 open end covers that size.
