2023 Ford F 350 Limited Lug Nut Torque & Bolt Specs

The 2023 Ford F 350 Limited lug nut torque is 165 ft-lbs (224 Nm), tightened with a 21mm 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: 21mm · Thread: M14x1.5.

This page is the OEM-referenced fastener summary for the 2023 Ford F 350 Limited. 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.

Common fastener categories on the 2023 Ford F 350 Limited

Wheel / lug nut torque and thread spec (covered above)
Brake caliper bracket bolts (typically 80-130 ft-lbs) and slide/guide pins (18-35 ft-lbs)
Engine oil drain plug torque — rarely above 30 ft-lbs; always use a new crush washer
Transmission pan, valve cover, and intake manifold bolts (low torque, often 89-106 in-lbs)
Suspension control arm, sway bar, tie rod end and ball joint torque
Spark plug torque (typically 10-15 ft-lbs on aluminum heads — do not exceed)
Differential cover bolts (RWD/4WD only) and transfer case fasteners

Repair guidance for this model year

For 2023 late-model work: Modern vehicles increasingly use aluminum body and suspension components. Aluminum fastener torque is typically 60-70% of equivalent steel torque, and aluminum threads strip easily. Use a calibrated torque wrench and apply anti-seize on any steel fastener threading into aluminum.

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

Frequently asked questions

What is the lug nut torque on a 2023 Ford F 350 Limited?

The OEM-specified lug-nut torque for the 2023 Ford F 350 Limited is 165 ft-lbs (224 Nm), using a 21mm socket on M14x1.5 thread studs. Use a calibrated torque wrench in a star pattern, in two passes (50% and 100%), and re-check after 50-100 miles of driving.

What socket size do I need for the 2023 Ford F 350 Limited lug nuts?

The 2023 Ford F 350 Limited uses a 21mm socket. A 6-point impact-rated socket is recommended over a 12-point chrome socket — 12-points round off lug nuts under impact-driver use.

Are the 2023 Ford F 350 Limited fasteners metric or SAE?

Metric is the standard for this vehicle. Most fasteners on this vehicle are metric (M6, M8, M10, M12, M14). Bring a full metric set; SAE substitutes can round the head. Bolt-head markings are the fastest way to confirm grade and material at the bench.
