What do I check for finish work: screw pattern and clean grille install?

Visible screws are tiny, but ugly screw patterns make finished HVAC work look amateur immediately.

Stop if

• Do we have the correct finish screws for these grilles, or should I wait instead of using mixed hardware?

Watch out

• Stop if the backing is missing, the grille will warp, or the hardware does not match the approved finish.

Check

• Start screws by hand or low speed when possible.
• Keep screw heads aligned and seated flat.
• Do not over-torque and dimple the face.
• Use matching screws when exposed.
• Clean metal shavings and fingerprints.
