Hello new here. I have a little project on changing my door threshold wood plugs out that are anchored in the concrete to hold the screws in place. The wood plugs are a little stripped and I would like to know what wood would be good or hard enough to do the job. They will be Epoxied into the cement. Its old school I know but that is whats there or is being used. Thanks in advance for any help, Mikie

If the threads in the wood are stripped & haven't held up for a resonable length of time, I would consider using heli-coil inserts in new pressure treated wood plugs with machine screws, otherwise I would just use PT plugs.

The "PT plugs" you refer to is I guess pressure treated wood and if so that wood would be way to soft, I would think something like a Hard Wood would be a better choice.

My preference would be heart white oak. It is both very strong and rot resistant.

I have some Red Oak and also have some White Oak so the white oak it is. As for making the plug I would think it needs to be so the screw would go through many layers of the growth rings in stead of having the screw splitting them or running through the same direction as the grain does. Right.
