Head of the grub screw stripped. Tried the super glue method to no avail. Has that ever worked? Anyhow, what's the next step? Try to drill it with a small bit or get some kind of screw extractor?

The head of the screw stripped or the threading in the box?

The threads stripped on my future box once. Tried a bunch of methods like heating the plastic and JB weld. None worked. Bought a grub screw the next size up and forcefully put it in which threaded the plastic in the process. That worked. Still holding a year later.

Screw head stripped not the box.

I think you get a screw head extractor bit. I've got one of these:


Which comes with 1 custom FCS Ezi Out bit for stripped screws.

Haven't used it but perhaps you can find just that sort of bit somewhere.

If it can hold a cracked engine block at pressure...it can do ANYTHING
It worked for a broken hinge on a door for a pretty good time frame with heavy traffic. Two kinds sold in tube: one with metal.and epoxy and other just epoxy. The epoxy one works great for ding repair while on vacation or in a pinch. Much better then suncure because only one step no sandiing if you form it right and smooth and remove extra before it dries.

Ended up getting a #8/#10 screw extractor from Home Depot. Drilled the grub screw a little with a 3/32 bit until the extractor could get deep enough to grab the Screw. I’d use this as a last resort because of the risk of damaging the box from drilling the screw. I would have used a little smaller bit, but my drill would not hold anything smaller. Never tried JB Weld or anything else to glue the hex wrench in.

So is it out?

I had a couple of secondhand boards that had badly speed Fut and FCS grubs. Very rounded so no luck with extractors.

I put a small Dremel bit against them and ran it at high speed. The friction caused the plastic to melt and I pulled the fin out then popped the grub out into the box. One or two of them didn't require filling and redrilling of the hole, but a couple did,I think I used epoxy putty.
