What is the thread pitch of the F250 lug nuts?
The standard thread pitch for Ford F-250 lug nuts is 9/16-18. That means the studs are 9/16 of an inch in diameter and have 18 threads per inch.
The F-250 Super Duty uses eight-lug wheels in most configurations, and aftermarket wheels or locking lug nuts can vary. Always verify the exact spec for your vehicle and wheels by checking the owner's manual, the wheel packaging, or Ford's parts catalog before purchasing replacements.
Common lug nut sizing for the F-250
All figures refer to the standard, non-locking lug nuts used with the OEM wheel setups on most 8-lug F-250 trucks. If you have aftermarket wheels or locking nuts, verify with the wheel manufacturer or Ford parts catalog.
- Thread size: 9/16-18 inches (0.5625 inches diameter with 18 threads per inch).
- Seat type: 60-degree conical seat common on many Ford trucks.
- Application: Typical for 8-lug F-250 Super Duty trucks, but confirm if your vehicle uses different wheels or a DRW setup.
For those who require precise confirmation, check the owner's manual, the wheel specification label (sticker on door jamb or inside glove box), or contact Ford customer support or a dealership parts desk. Using the wrong lug nut size can damage threads or wheels.
Additional considerations
Some F-250s equipped with specific aftermarket or OEM locking lug nuts may use a different thread pitch or seat style. If you are replacing lost lug nuts or installing new wheels, ensure compatibility by cross-checking part numbers or measuring the studs with a thread gauge and caliper.
Summary
The standard thread pitch for typical Ford F-250 lug nuts is 9/16-18, compatible with the eight-lug, heavy-duty wheel configuration seen on most models. Always verify with your vehicle's documentation or the wheel supplier when dealing with aftermarket wheels or locking lug nuts.
