Goldtec Hub Bolt issue

Hey guys

I need some help and rather urgently.

I have managed to damage my rear goldtec hub bolt. So i have 3 issues.

1. I cannot seem to get the bolt out. the edges inside where the allen key is supposed to go are almost rounded. How do i remove the bolt? I dont want to try to much right now because i suspect that it is almost (if not already) impossible. What methods can i use without causing the bolt to be permanently stuck in the hub?
   
2. I ordered M6 Ti bolts as replacement but when i compare it to the one on the otherside that i just barely managed to get out, they are *NOT * the same diameter. The length is 25mms. What bolt is the correct size bolt for the rear Goldtec Pro hubs??
   
3. The last issue is im hoping that there is a solution that i can use by Saturday morning as im supposed to be riding on a long journey to a booked B&B.
   
   

Please guys can you help,

If the Allen key fitting is fucked it may have to be drilled out.

The bolts are made of cheese, I put in a new one from Goldtec a couple of weeks ago and it is already showing signs of rounding out.

Otherwise that whole washer thing may need to be squeeze to crimp around the Allen bolt and then twisted off.

It's a screw not a bolt. You could try gluing/soldering the allen key in the hole?

Also I haz spare screws for shop14 trick hubs (made by goldtec) pretty sure they're the same rear diameter so you're welcome to have one if/when you manage to ge the old one out. Is the allen key you are using a good quality one? Cheap tools aren't made to such close tolerances so using a higher quality one may fit slightly better and allow you to remove said screw.

If you aren't bothered about the hollow top hat shaped washer you could saw a slot in it (and the screw head) and use a flat head screwdriver to loosen the screw.

M6 sounds about right, check their website. Hacksaw a slot into the head of the screw and use a screwdriver to undo it.

I can lend you a rear wheel if you can't fix it for the weekend, provided you can get it out of the frame. You'll have to leave your hipster haven to collect it though ;)

Um yeah, what Moog said... Slow on the uptake today.

It's a screw not a bolt.

Funny fucking hub.

I had the same trouble last year, did the hack saw and flat head screw driver thing worked a treat.

m6 bolt not a screw :)

Whilst your post wasn't wrong I'm pretty sure you are implying I'm wrong in what I said in my first post. I'm not.

Cheers guys!

M6 cant be right cause i have the ti one here and its definitely smaller than the one for the back hub...

James is right though, its made of cheese. The tools are decent ones, but turn easily.

I can try cutting a groove, but it will be through the outer protective cap thingy too. Worth a shot!

Guys, a replacement/ stand in bolt or wheel would be awesome!

Only issue is that was my only working bike, so problem getting to you guys :-( Once i get it off, then i cant fit it back without the bolt or wheel...

I'm in E1 if that's walkable for you.

And it's a fucking screw not a bolt

Ian

is the thread incorrect? there are various lengths of m6 bolt

http://www.chainreactioncycles.com/Models.aspx?PartnerID=79&ModelID=43469

as far as i understand it the M6 refers to the threads, there can then be different size allen key heads

so gold tech use a 6mm allen key for the rear one but a 5mm allen key for the front, - not sure if the tpi is actually different for both

ed

possibly technically it may be a screw but if you google m6 bolt you get things that either need a spanner or an allen key

if you google m6 screw you get things with a similar thread but the end either takes a flat or posidrive screwdriver

James, that is exactly the one that i have sitting on my desk. It fits the 5mm allen. (wish they said that on the website)

So M6 is thread, thats good to know!

ed did study some engineering so could well be right

I'm in E1 if that's walkable for you.

E1?!?! Thats close enough to walk!!!

Im E2 :-)

I'm right near clapham junction station which can be reached easily from everywhere in the known universe. I would deliver it but I'm super busy at work..

It's a bit of a grey area to be honest, I'm just being a pernickety cock spot.

They are called cap head bolts. Fact*

*Lies

I thought that a screw generally has better tolerances than a bolt + a bolt is traditionally a hex-shaped head.
This will bug me ed - what is your opinion?

Cap head screw

I was wrong. It's been known to happen..

Bolt - tightens with a when combined with a nut or has a hexagonal head which you use a spanner/socket on.

Screw - Everything else*

*apart from some specialist threaded fastenings which use the term bolt just because

By no means comprehensive but it works for me.

wiki

" hex key or Allen key (also known by various other synonyms) is a http://en.wikipedia.org/wiki/Tool that have a hexagonal socket in the head (internal-wrenching hexagon drive)."

so it seems interchangeable

i am wondering if the goldtec screws/bolts are actually designed for imperial not metric allen key.

Could this explain why we manage to round them out?
