Are these aluminum lug nuts safe for everyday driving?

Aluminum lug nuts are fine for street use and show cars. If you tow or run track duty, steel is the stronger choice — check your vehicle manual for any restrictions on material type.

Will these work with my OEM wheels or only aftermarket?

M12x1.5 is the standard thread pitch for most passenger vehicles. The extended acorn design clears modern wheel designs. Test-fit one before committing the full set to make sure the profile matches your wheels.

Do I need to torque these differently than factory lug nuts?

Torque specs are the same — refer to your vehicle's service manual for the correct pound-feet value. Aluminum won't change that number, but it can strip easier if over-torqued, so respect the spec.
