Sora hollowtech left crank bolts needed..

[Arjimlad]

Although I am careful, I have burred the head of one of the bolts on the left crank which hold it on.

There are two 5mm allen headed bolts which have to be undone to access the BB.

Any ideas where I could get replacements from please ?

I believe I have a
Shimano 'SORA' FC-3450 compact chainset 9-spd, 50/34T


Many thanks !

Shimano techdocs show them as M6 x 19. Local hardware shop? Halfords? Ebay? Screwfix?

M6 x 20 stainless individually here... http://www.titanbolts.co.uk/acatalog/M6Socket_Cap_Head.html

But I'm paranoid about having the correct spec for load bearing parts, so I'd be asking the local bike shop to order in the correct Shimano part, Y-1G3 98010, listed in the techdoc.

Thank you. That exploded drawing indicates to me that the BB on my bike (new in Feb) may not be correctly assembled, which might be the reason why the damn thing keeps sounding like a pepper mill. LBS job, I think.

And it's the pedals. Nothing to do with the BB, cranks or anything else. New in February and knackered by May... have contacted ebay seller.
