Bolt torque, grades and vehicle specs, sourced

Automotive torque specifications

Vehicle torque values quoted from the manufacturer, with the document and page. We cover wheel lug nuts for 31 popular US vehicles by model year, spark plugs by thread and seat from the plug makers, and oil drain plugs where the owner's manual prints them.

Where these numbers come from

The rest of this site calculates bolt torque from proof load and a nut factor. This section does not. When the vehicle or part maker publishes a torque, that figure wins, so every value here is quoted as printed from the maker’s document: the owner’s manual, a service manual or a plug maker’s chart. Each row names the document and page, and opening it shows the exact wording. We don’t convert units or round, so you will see Ford’s 150 lb.ft (204 Nm) next to a Toyota 76 ft·lbf (103 N·m).

When a manual is missing, we say so. Several recent Toyota manuals and some early Honda and Hyundai manuals were not available to us. For those years we publish no value rather than carrying an older one forward.

What is in this section

  • Lug nut torque by vehicle: model-year tables for 31 vehicles. Each one shows the stud size where the manual prints it, the re-check distance and the thread instructions. There are make charts for Ford, Chevrolet and GMC, Jeep, Toyota, Honda, Subaru, and Hyundai and Kia.
  • Spark plug torque: installation torque by thread size and seat type from the plug makers.
  • Oil drain plug torque: published only where the owner’s manual prints it. In our set that means Honda and Nissan. Most other US owner’s manuals don’t print it.

For a fastener the vehicle maker doesn’t list, the bolt torque calculator gives a general value by size and grade. Use the manufacturer’s figure whenever one exists.
