2008 Honda Civic Lug Nut Torque & Bolt Specs

The 2008 Honda Civic lug nut torque is 80 ft-lbs (108 Nm), tightened with a 19mm socket on M12x1.5 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: 80 ft-lbs (108 Nm) · Socket size: 19mm · Thread: M12x1.5.

This page is the OEM-referenced fastener summary for the 2008 Honda Civic. 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.

Honda's lug-nut torque sits at 80 ft-lbs (108 Nm) for nearly every passenger model from 1998 onward, with an M12x1.5 thread on most cars and the larger 14mm thread on Ridgeline and Pilot. The 19mm socket Honda uses is one of the only OEM oddities in the Japanese lineup — bring a 19mm with you, not just a 21mm. Honda factory torque values for engine oil drain plugs are unusually low (29 ft-lbs on most engines) and the crush washer is single-use, so replace it every oil change.

Common fastener categories on the 2008 Honda Civic

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 2008 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

Frequently asked questions

What is the lug nut torque on a 2008 Honda Civic?

The OEM-specified lug-nut torque for the 2008 Honda Civic is 80 ft-lbs (108 Nm), using a 19mm socket on M12x1.5 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 2008 Honda Civic lug nuts?

The 2008 Honda Civic uses a 19mm 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 2008 Honda Civic 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.
