I have an aluminum fuel tank which has about a 6-8" inspection cover
made out of the same material. The cover screws through a rubber
type gasket and the screws are threaded into the tank material. One
or two of the screws have stripped the threads and the tank weeps
diesel primarily when it's completely full. Basically I think that I
have 2 options to repair this.

1) Redrill/tap with larger screws
2) JB Weld a nut on the inside.

Any comments/suggestions?

&oi=spell&resnum=1&ct=result&cd=1&q=clinch+nut&spe ll=1 for thinner
panels.

Heli-coils for thicker plate, typically 2x thread diameter.
Both generally need a tool to fit.


Considering that I only have 2 screws to repair, I really don't want to
purchase a specialized tool. The helicoil is for much thicker material
than I have. However, thanks for the suggestion.

Perhaps oversize:

Stronger than pre-tapped holes due to work hardening and tight fit.
