2023–2025 Buick Envision 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 2025 Buick Envision. 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 2023 and 2024 model years — identical specs on file for each year.

Field evidence: Lug nut torque is not verified; no specification is assumed. Lug nut socket size is not verified; no specification is assumed. Lug nut thread size is not verified; no specification is assumed. Lug nut part number is not verified; no specification is assumed.

GM passenger cars, crossovers and trucks use different wheel hardware families, including seat-style differences that matter when buying aftermarket lugs. Match the listed row and the original seat type; do not infer a truck value from a car, or the reverse.

Common fastener categories on the 2025 Buick Envision

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 2025 late-model work: Modern vehicles increasingly mix aluminum, high-strength steel and coated fasteners. Use the exact fastener record and service-manual procedure for the joint you are touching; do not adjust torque or add compounds unless the procedure calls for it.

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 2025 Buick Envision?

Specification not verified for this lug nut summary. Do not substitute another model year's value. Field evidence: Lug nut torque is not verified; no specification is assumed. Lug nut socket size is not verified; no specification is assumed. Lug nut thread size is not verified; no specification is assumed. Lug nut part number is not verified; no specification is assumed.

What socket size do I need for the 2025 Buick Envision lug nuts?

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

Are the 2025 Buick Envision 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 Buick Envision years

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