stripped TB screw what do you suggest
i bought a used ported throttle body recently and just installed it yesterday. the idle hole was drilled out a bit for a larger cam so i swapped my stock blade in. i tightened the second screw and stripped it. still stays kinda tight but i dont wanna suck it through the engine.
what would you do?
the shaft is cut in half so the stock screws stick out the back a ways. i have some small nuts that fit the screws. just wouldnt want them vibrating loose either.
could also loctite the screws in but will the heat/oil wear it away?
orrrr just buy a screw tap?

first you may want it a bit loose to keep the TB blade from sticking, don't tighten it down too heavily. I used loctite on mine with no issues. I'd also just tap for a larger screw, not a big deal.

If the shaft is cut in half you don't want nuts on that edge anyway. Might as well swap in a stock shaft. I you do use a shaft like that the bolts should be cut to length. and use loctite

hahah thanks for the help. chances are it wouldn't have fallen out anyway but i didn't wanna risk it. used some loctite and now it's really in there.
i had to use the stock scews even with the ported shaft because the tb only came with one and the head of it(allen key) stripped when i tried to remove to swap blades but of course the head of it stripped and i had to cut a slot and wedge a flathead into it to remove it.
has nothing to do with the topic but the adjustable bump stop screw was stuck too so i ended up having to drill that out and when i rethreaded it that bolt stripped too so i had to drill it out a second time and then i just used a small nut and a bolt.
just about every nut and bolt on it stripped at some point or another hahah.

feuture refrences if something like that ever happens again buy yourself a heilicoil kit and repair the threads to the origional size this way you dont have 2 different size bolts in one part it makes it easier to take things apart because then you dont need 2 different wrenches to unbolt one part
