Striped screws in plastic

[ZRXRICH]

What glue can you use to fix a striped screw hole ? Thanks Rich

Bigger screw? Depends on the material and its function. I have filled with jb weld, drilled and tapped before. I have also installed a helicoil. It all depends oh how much room there is to work with. I have also threw something in the hole (thin plastic, heat shrink, wire insulation, etc) and then inserted the screw if its just something to "make work".

What's your application?

In abs type plastic like most tamiya parts you can use model glue add a drop and work around the threads with a toothpick or whatever and let dry. For nylon parts crazy glue works well especially with steel screws.

I have used most of the methods mentioned. I have also used Thread lock, blue. Plumbers tape will help as well.

BLACK plastic parts i use LOCTITE 2 PART EPOXY.cANT TELL REPAIRED IF DONE RIGHT.You can drill it and tap it.DON

I would probably fill the hole with something strong, maybe JB Weld or crazy glue, then drill a new hole with a bit that's one size smaller than the intended screw (i.e. if it's a 3mm hole you want to tap, then drill a 2 or 2.5mm hole), then tap the hole to the correct size.

For relatively soft materials up to and including aluminum, you can make your own tapping tool by taking a screw the size you need to tap, and using a Dremel cutting disk to cut 2 tapered notches in the threaded end of the screw, at 12 & 6 o'clock. Then you take that tapping tool and screw it into the hole, backing it out frequently and blowing the tapped-out powder & bits, and repeating, turning in a turn or two more each additional time until the desired hole depth is achieved.

I used that method several times to tap my own screw holes for things like the ball studs to mount a stabilizer ball-end on these GPM alloy arms, which had no holes on the trailing surfaces.
