Stop adding screws. Correct stripped or distorted fasteners if allowed, restore the joint fit, and ask before turning a clean S-and-drive joint into a warped leak point.
Use screws only where the shop/project detail calls for them. Random screws can distort the joint or create more problems.
Ask when the joint is warped, screw holes are stripped, the duct is thin, or the spec requires a specific fastening pattern.
Watch out
Do not over-screw, strip, distort, or use screws to make up for a bad fit.
Check
Verify screw type/location if the detail requires it
Check for distortion, stripped holes, and seal path issues
Steps
Stop driving more screws.
Check if the metal is pulled down, stripped, or oil-canned.
Back out/replace bad screws if directed.
Re-form the area enough to restore fit if possible.
Ask if the joint needs rework or replacement.
Say this to your foreman
In Rectangular Duct Assembly: S-and-Drive, I'm looking at: I over-screwed or distorted the joint. What should I verify before I cut, drill, seal, cover, move, or install?
