Grub screw problems

Any discussion on shaping, designing, repairing and riding surfcraft of any type or shape. Also a good place to ask the 'what board should I buy?' question.

Grub screw problems

Postby jonnydance » Mon May 25, 2009 2:50 pm

Hi, I'm off to Portugal on Friday and had my board out today to check it over. Unfortunately one of the screws holding in my fins is wrecked - the hexagonal shape inside the head of the screw where the fin-key fits is completely ground out and so the fin-key just spins, and doesn't remove the screw. I need to get the fin out as I'm taking my board out on the flight with me, but don't know how to go about it. Any ideas to help me reomve it would be wicked - cheers guys and gals!

use sun cure or superglue on the head of the fin key, leave to set in stuck grub screw, then unscrew grub from board, get key out of grub screw, buy more screws from here --> http://store.magicseaweed.com/FCS-Fin-Screws/Item/287/ they will be with you tomorrow, bob is your uncle, fanny is your mum's sister.

super-glue an allen key or something into the grub screw slot and unscrew it.

or try a futures key on it, there slightly bigger it might work

Just use an oversize allen key, if your neighbour can't lend you 1 just go to a hardware shop with an fcs key and get 1 slightly bigger. And next time don't tighten so much as it not only wrecks the screws but increases chance of damaging the plug if you catch your fins on the reef or whatever. Good luck.

Also worth a try

Cut / file 3 or 4mm of the end of your key. As well as damaging the grub screw you may have damaged the key. Also the hexagon in the bottom of the grub screw is probably still OK so a clean key may get it out to replace it.

As above - key is more likely to be trashed than the grub screw. Buy a proper allen key of the right size and you should be fine (forgot what they are but they are imperial - 3/16" sounds familiar??). Otherwise it's the superglue option...

Thanks for all the replies guys - unfortunately I'm still no nearer getting the damned thing out.
Larger allen keys don't work, I've tried flat-head, philips and those star-shaped screwdrivers to see if they'll get a bit of purchase, all without success. My old man posted me a reverse-threaded screw to draw it back out, which I've tried manually and as a bit in my drill, again nothing as it's marginally too wide to fit into the hole deep enough. I've even got angry and tried drilling the crap out of it!
Unfortunately the inside of the screw is so rusty it's damned near impossible to get anything to grip successfully...
I've been into hardware shops to seek advice, and all over the Internet. Unfortunately my local repair guy is away on holiday, and all the local surf-shops use him too so they're no use at present!
My last options are the superglue trick, which I'm reluctant to try in case it seeps out into the hole and sets the screw permanently, or to simply pack the board with the fin still in using loads of bubble-wrap and foam and hope the fin makes it out there in one piece - either way I can then get the screw removed by a surf-shop when I get there.
Thanks again, and if someone does come up with a Eureka moment this afternoon I'll be eternally grateful!

superglue mate, you just have to use a tiny blob and be careful wth it, obviously if you squirt a cubic ml of glue in the hole it is gonna stick the whole thing but if you only use a tiny bit on the head of the allan key then you should be fine. What is the wrost that can happen? Either you get the screw out and it is fine or you don't and you have to get the fin plug replaced. If you don't try the glue option you'll end up having to get the plug replaced anyway, probably!

good luck!

i am aham fisted twat and used to always shread my grub screws...i remember once pulling up to TE at dawn double overhead and no one in...depserately trying to swap some fins over and just fuckin everything up..very stressfull..

in the past ive tried both the solarex and the super glue method and both didnt work. has anyone HONESTLY done this sucesfully??????

i just drill mine out these days

and make sur e you use a standard allan key ratchet to tighten which seems to presevre the screws much better than those daft keys.

If your absolutely desperate to get it out hold a piece of wire with pliers and heat it up and then try to melt round the grub screw to get it out. You ll then have to drill and tap another screw hole from the other side. I would only do this if i was really really desperate.

If your going to leave the fin in the board put the others in, pack between them with polystyrene not bubble wrap and wrap the whole lot round with duck tape. The more solid you can make it the less chance the fins will get broken.

All that sounds like a lot of fucking about, just get an opposite size key set e.g. Imperial if screw is metric and vice versa chose the size just bigger than the original tap it home with a small hammer and bob is your uncle, or get an old small terminal screw driver file it to just over size of the hex and again job done.

when you replace the grub screw put a little petroleum jelly on to avoid it seizing again

:roll:

and get your next board with glass-ons or Lockbox :lol:

Put cocoa-cola on it - leave it to soak for 20 mins - cut Fin Key down so no rounded edges on hex ( as previously suggested) put key in grub screw as far down as possible then tighten it sharply 1/4 turn , then unscrew that little chap outta there 8)

never had a problem with that - they put the swallows of my fish, through the pipe lagging, through the endo of the board bag and chipped the corners, i dont't mind that though, i wonder how many people on here know that a fish should be stood on its nose and not the swallows :-D

not really just use a proper sized decent quality hex key in the first place

the free ones sent out with fins are often rubbish (which is a fault)

gte a fcs tool - it has proper hex and a reamer tool to remove tough ones

if you take fins in/out regulary use new hex boltz occasionally

what about dipping the key in a bit of arildite rapid. would fuse the screw and key together like concrete.

Either that or there is some stuff called chemical metal.

I'd just like to say...


arrgggghhhhhhhH!!!!!! :evil: :evil: :evil: :evil:

:cry:


Anyone know if I drill the little bugger into the plug will it fall out, or is the grub too long to do this and I'll just wedge it in more?

PS. superglue is a fail. solarez is a fail. FCS ratchet reverse screw thing might as well have been a flaccid penis

Warm the plug up with a hair dryer, go steady though. with the fcs reverse thread thingy push it in as hard as you can and turn it really slowly.
If it slips push it in really hard and then force it to the side slightly while turning slowly.

So I warmed up the receptacle, inserted my flaccid penis substitute, tried giving it a small screw to the left, pushed it slightly to one side then the other. Tried pushing it a bit harder. All that happened was I made a right mess of the entrance hole :-(

I may have to call by and see if you can work your magic mate. I know how much you like fixing plugs in the summer :D Don't be surprised if I bring my whole quiver for you to make beautiful again.

wd40?? might loosen 'er up a bit when you wanna give it a slow screw to the left...

You'll hate this but I usually grease my new fcs plugs with a wee spot of vas before use, seems to keep them screws nice and smooth for a good long time :)
