2009 Hyundai Elantra Lug Nut Torque & Bolt Specs

The 2009 Hyundai Elantra lug nut torque is 80 ft-lbs (108 Nm), tightened with a 17mm 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: 17mm · Thread: M12x1.5.

This page is the OEM-referenced fastener summary for the 2009 Hyundai Elantra. 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.

Hyundai/Kia lug-nut torque is 79-88 ft-lbs on nearly all passenger models, M12x1.5 thread, 21mm socket. The Tucson, Sportage, and Santa Fe all use the same fastener spec. Hyundai's oil drain plug threads are unusually fine-pitch and strip easily — always use a torque wrench, not feel.

Repair guidance for this model year

For 2009 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 2009 Hyundai Elantra?

The OEM-specified lug-nut torque for the 2009 Hyundai Elantra is 80 ft-lbs (108 Nm), using a 17mm 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 2009 Hyundai Elantra lug nuts?

The 2009 Hyundai Elantra uses a 17mm 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 2009 Hyundai Elantra 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.
