Common fastener categories on the 2016 Mazda CX-9

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 2016 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

What socket size do I need for the 2016 Mazda CX-9 lug nuts?

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

Are the 2016 Mazda CX-9 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.
