Will these work on my wheels with a different lug pattern?

M12x1.25 is a standard metric thread size. As long as your wheel studs are M12x1.25, these will thread on. Confirm your stud thread size before ordering — mixing thread pitches will cause cross-threading.

Do I need to torque these to a specific spec?

Refer to your vehicle's service manual for the correct torque value — it varies by manufacturer and application. Acorn nuts seat differently than conical lugs, so don't guess. Most vehicles run 80–120 ft-lbs, but your manual is the only source of truth.

Will the orange finish scratch or fade over time?

Anodized aluminum holds color better than paint, but it will show contact marks and micro-scratches from wheel mounting and road salt. It won't peel like powder coat, but maintenance washing keeps the finish looking fresh.
