Type of Bolt that broke: 10pcs Engine Valve Cover Screws Bolt For Hyundai & Kia 224512G600 22451-2G600 | eBay

Ok, So as the subject says, was putting the bolts back in and snapped off one, my fault! so i tried to drill it out and use and extractor but it just tore the bolt up more and more i would catch and feel like its coming out but was really just tearing it up..

My thought its to drill it out and just re-thread? I wanted to check here first to see if i had any other options. All other bolts are find its just this one.

Thanks in Advance.
