2001 Ford F 350 Super Duty Lug Nut Torque & Bolt Specs

The 2001 Ford F 350 Super Duty lug nut torque is 165 ft-lbs (224 Nm), tightened with a 22mm socket on M14x1.5 studs. Torque in a star pattern in two passes (snug, then final), and re-check after the first 50–100 miles of driving. Use a calibrated torque wrench — not an impact gun — for the final pass.

Lug nut torque: 165 ft-lbs (224 Nm) · Socket size: 22mm · Thread: M14x1.5.

This page is the OEM-referenced fastener summary for the 2001 Ford F 350 Super Duty. Use it before any maintenance or repair job where torque values matter — brake work, wheel changes, suspension service, engine teardowns, or oil changes. Specs are pulled from manufacturer service literature, cross-checked against community data, and updated as new chassis variants become available.

Ford lug-nut torque varies more by chassis than most makes — 100 ft-lbs for Focus/Fusion/Fiesta, 150 ft-lbs for half-ton F-150, and 165 ft-lbs for Super Duty F-250/F-350. F-150s from 2004-2014 use a 21mm OEM socket, while 2015+ aluminum-body trucks moved to the larger 22mm. Ford torque-to-yield (TTY) head bolts are standard from the early 2000s — do not reuse them, ever.

Repair guidance for this model year

For 2001 model-year work: Always use a calibrated torque wrench for safety-critical fasteners, and replace lock washers and crush washers on every reassembly.

Tools you will need

Metric socket set (8mm-22mm), 6-point impact-rated
Calibrated torque wrench (10-150 ft-lbs covers most automotive jobs; add a 0-250 ft-lbs wrench for truck lug nuts)
Breaker bar (24" minimum) for initial loosening
Penetrating oil (PB Blaster or Kroil) for any fastener over 5 years old
Anti-seize on stainless or dissimilar-metal threads; thread-locker (Loctite blue) on critical reassembly
