2017–2018 Dacia Duster Bolt Sizes & Torque Specs

Lug nut torque is not verified for this summary. Review the cited evidence and exact hardware application before installation.

This page distinguishes source-backed fields, unresolved conflicts and unverified legacy records for the 2018 Dacia Duster. Match the exact hardware and manual conditions before maintenance. A source for one field does not verify the other specifications.

These specifications also apply to the 2017 model years — identical specs on file for each year.

For the 2018 Dacia Duster, fasteners follow application-specific metric or SAE standards typical of late-model Dacia engineering. Always confirm spec against the factory service manual before tightening safety-critical fasteners (suspension, brake, steering, head bolts).

Common fastener categories on the 2018 Dacia Duster

Wheel / lug nut torque and thread spec (covered above)
Brake caliper bracket, mounting, and slide/guide-pin bolts are different fasteners. Confirm the exact axle, application and service-manual specification before reassembly.
Engine oil drain plug torque and tool size when this vehicle has a verified drain-plug record
Transmission pan, valve cover, and intake manifold bolts where the database has exact records
Suspension control arm, sway bar, tie rod end and ball joint torque
Spark plug torque only when a vehicle-specific spark-plug row is available
Differential cover bolts (RWD/4WD only) and transfer case fasteners

Repair guidance for this model year

For 2018 model-year work: This era introduced widespread torque-to-yield (TTY) bolts on head, main, and crank pulley fasteners. TTY bolts stretch permanently when torqued and must not be reused — the spec calls for a fresh bolt every time. Always verify TTY status against the FSM before reassembly.

Tools you will need

Metric and SAE socket set (8mm-22mm plus 1/4"-7/8"), 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
Replacement washers, threadlocker, anti-seize, or dry-thread preparation only when the exact service procedure specifies them

Frequently asked questions

What is the lug nut torque on a 2018 Dacia Duster?

Specification not verified for this lug nut summary. Do not substitute another model year's value.

What socket size do I need for the 2018 Dacia Duster lug nuts?

Confirm the socket against the actual lug nut; no size is assumed here.

Are the 2018 Dacia Duster fasteners metric or SAE?

Metric and SAE hardware can both appear on one vehicle, depending on the component and exact application. Use the individually verified field and the actual fastener or service manual rather than inferring a standard from the model year, make or generation. Bolt-head markings can help identify the hardware at the bench.

Other Dacia Duster years

Same model, different model year — fastener spec may change. Always confirm against the year for your VIN.
