U-Bolt Torque Table

Recommended U-Bolt Torque for Cold-Formed U-Bolts

Cold-Formed U-Bolts which have been torqued to a set preload are recommended to be re-torqued after a short time to take up the stretch in the set of the material.

U-Bolts that have been well lubricated with an anti-seize compound will have a torque range between plated and unplated values. All the below values are general guidelines.

The OEM Service Manual on specific models always takes precedence over values shown.
