2G FIAV Screws removal (SOLVED)

[MasterMatt209]

So I’m doing a TB rebuild and while taking off the FIAV screws I got all of them except the one in the middle that would be impossible to get vice grips on or anything. It’s starting to strip does anyone have any advice at all on how I could remove this screw? I’m thinking about buying one of those stripped screw removeres from Lowe’s tomorrow, but I’d love some feedback from you guys.

Impact driver will work sell here, these things are a pita to remove and sometimes get lucky, j did one and was ok, my other and a few wont budge

Yes, use a impact screwdriver, when tapped with a hammer the force will break it loose, if it's stripped bad I would spray it with aerokroil, or pb blaster, also using valve grinding compound in the head creates grip and use a good bit or a bit with teeth on them, if that fails, drill the head with a #30 and use a snapon/hanson extractor.

As stated above use a impact screwdriver but if the head is totally wasted just simply drill off the head of the screw. Drill until the assembly pops off. Since it's the last bolt you should feel it pop. Vise-grips will easily take care of the threaded portion because there is no torque on the bolt anymore. Had this happen twice.

I did this recently and had the center bolt screw strip with an impact driver. So if that fails, what I did was use a sharp chisel to create a groove in the top of the screw, then used a dull chisel to tap it counterclockwise.

Success! Thanks all of you for the advice, I ended up going straight for drilling the head off of the screw and it worked like a charm. I used a flathead and a hammer to know the head off after drilling it and the FIAV came right off. Funny part is I was able to unscrew the rest of the screw by hand very easily. I’m thinking it was the washer or soemthing that made it so hard to turn. But thank again for the help guys

When I drilled mine out same deal, came out by hand once the tension was off it.
