Snap-on IZ27IR14X18 Insert Ring, 27 mm Closed Ring for 14 x 18 mm IZO Bodies

Description

M18 bolts hold down pumps, motors and press frames, and their nuts measure 27 mm across. The Snap-on IZ27IR14X18 insert ring closes around that hex and plugs into a 14 x 18 mm IZO/ISO receiver. So a heavy electronic body can tighten M18 joints with the ring wrapped around the nut.

Where the 27 mm ring sits

Because 9 x 12 rings end at 19 mm, the IZ27IR14X18 needs a 14 x 18 body. Also, ISO 4032 and DIN 934 agree on 27 mm for M18, so one ring covers both.

Torque headroom for the Snap-on IZ27IR14X18 insert ring

CAT1500i prints no working torque for its insert rings. Therefore the body decides the ceiling. The ControlTech CTECHBN340A reads 17.0 to 340.0 N·m, or 12.5 to 250.8 ft-lb. If your M18 spec runs above 340 N·m, this body cannot reach it, so plan another method. Below 68 N·m, the reading also falls outside Snap-on’s 20 to 100% calibration band.

Pump base job with the IZ27IR14X18

Picture a pump skid with four M18 hold-down nuts, painted after assembly. An open jaw would bite the paint on two faces and could slip under load. The closed IZ27IR14X18 wraps the hex instead, so the pull stays steady. Then the ControlTech body keeps each result, since it stores up to 1,500 readings for later download.

Keeping the Snap-on IZ27IR14X18 insert ring true

• Clean the rectangular shank and receiver before each swap.
• Drop the ring fully over the nut, not just onto the corners.
• Choose the stored head-length factor for this ring on the body.
• Never crack seized nuts with it, as Snap-on warns.

Snap-on also notes that periodic recalibration keeps the body accurate, so book it with your IZ27IR14X18 kit.
