As the title states, the screw holes in my metal door frame are stripped out and do not hold the screws for my strike plates. The door is a finely made iron and glass door (heavy), but the metal for the frame is fairly thin. I thought about doing a helicoil, but I think the metal may still be too thin to hold a good coil. Any ideas on a solution that will look good (this is my entry door)? Thanks!

If you have sufficient space behind the material in which the hole has stripped, you may be able to make use of a rivnut. It's a threaded insert which matches the required threads (machine screw, not sheet metal or wood screw) and requires a larger hole to be drilled. Once inserted, the tool compresses the back side in the same manner as a pop-rivet or blind rivet and secures the threaded portion for return to normal use.

The image above shows a metric version available from Amazon.com, but SAE sizes are also common enough. Some tools for installation can be expensive, or as simple as a wedge with a bolt to apply the proper force.

The above, also from Amazon.com is obviously not a wedge type, but is not the hundred dollar version.

Can you use a tap and die set to enlarge the hole to the next size that would work and upsize the hole in the strike plate to accommodate a larger diameter screw for the upsized hole?
