Thread tape?

dasfi, Oct 28, 7:16am
Cannot tighten a screw, will it work if i put a few layers of thread tape around it first!

Nope. Use a bigger screw or fill the hole and re drill and tap it.

Bugger, was trying to avoid that

You can also use a screw with a left hand thread as this will work also, but you cant get left handed thread tape so dont try that.

"Wrong" - you can get left handed thread tape!
ralphdog1, Oct 28, 7:49am
You don't need to buy left handed thread tape, that is just a dishonest marketing con.
Just turn the right handed stuff over and use the other side.

Sweet as will try tapping it slightly bigger, didnt really want to as its the screws that hold my Nitro rc motor to the chassis, and the motor is alloy, and dont have much room for error
petermcg, Oct 28, 9:40am
What are you screwing to is the chassis alloy or plastic.

If its something like that just chuck a bit of thread tape on it. Its only a RC car

Have you actually removed it to see if it's the screw or the hole that's buggered!
dasfi, Oct 28, 10:14am
chassis is also alloy, holes in motor are getting a little flogged out
petermcg, Oct 28, 2:02pm
You may be able to drill the hole a bit deeper in the chassis, tap it out and use a longer bolt.

If they're not blind holes or can be converted to through holes with access to the back, put a nut on it.

Thread tape (and thread paste) is designed for tapered threads, commonly used on pipe and for tube fittings, it fills in minor flaults in the thread form that can allow leakage even when correctly tightened. The best solution for standard threads (non-tapered) is loc-tite or similar products, however the amount of damage and usage you have described above will require a more permanant fix much as MH_T says above.

Try knead it or similar if it is just a toy.

put a fine coat of soap on the screw, mix some 5 minute epoxy ,put it all together with the screw at interferance, leave it overnight and the screw should have a new seat to screw into or just leave it screwed up till next time you have to unscrew it.

If it is holding a motor in you may need to have it LVV certified for your next WOF

yup i'm pretty sure a nitro conversion needs a cert.

go to mitre10 or such and check out tech screws,some have a coarse thread that you can fit in the original stuffed hole
