stripped bolt on preesure relief valve

[Finley]

Managed to strip out one of the 10mm bolts on the above while replacing parts.
What do you recommend using to repair in this application? There seems to be a fair amount of spring tension on the cover so I'm not sure if I need to drill and tap larger or what.
Thanks for the help.

Get a proper sized heli-coil set, this will help you keep the OEM sized bolt.
