Cummins ISX head bolts require multi-stage torque + angle tightening at 400+ ft-lbs. Short sockets flex. Thin walls round off bolt corners. No angle markings means guesswork. The result? Uneven clamp load across 24 head bolts = gasket failure in 5,000 miles. ATC24MMISX-A solves every one of these problems:
- 5″ length eliminates flex during long torque pulls
- Heavy-wall 6-point grip prevents bolt corner damage
- Permanently etched 90° markings for precise angle turns
- ¾″ drive matches your shop's heavy-duty torque equipment
Complete ISX Head Bolt Torque Sequence
Follow this proven workflow using the ATC24MMISX-A socket:
- Prep: Clean block deck, verify head flatness, install new head gasket per Cummins spec.
- Stage 1: Hand-start all 24 head bolts in correct sequence using ATC24MMISX-A socket.
- Stage 2: Torque to 50 ft-lbs using ¾″ drive torque wrench + ATC24MMISX-A.
- Stage 3: Torque to 110 ft-lbs, then align etched 90° mark for angle turn.
- Stage 4: Final 90° + 90° angle turns using socket markings as reference.
- Verify: Recheck all bolts in reverse sequence after 30 minutes cool-down.
