Wanted 4x Headset and Stem bolts for 2010 Specialized Globe Vienna 01 Ladies Stepthrough

[JimmieR]

Would anyone have 4x new Allen bolts for the headset and stem for a 2010 Specialized Globe Vienna 01 Ladies Stepthrough, as shown in the photos below?

I bought new replacements from the Nut & Bolt Store in Hove but unfortunately the head size is too large (by 2mm) to fit in the recesses where the bolts go. I've also tried Evans Cycles and Rayment Cycles (Brighton & Hove's two Specialized dealers) but to no avail.

Perhaps someone might be able to direct me to a place that could sell them to me even if they don't have these bolts themselves.

Thank you.

Jim

I'm assuming you're looking for M6 x 20mm socket cap screws as they are the most common size I've found for stem bolts. I've used this seller on ebay for this sort of item and they give dimensions of each part which you may find useful.

Hi Rikster!

Thank you for this information but I believe I've already tried this great site or similar ones. I was told that the originals are specially commissioned Specialzed bolts with smaller heads than normal socket cap screws of this size. I think they are M8 socket cap screws with M6 heads on them. That's my problem.

They were a bit difficult to photograph but hopefully you can see that the threads are a good match with the 'new' socket cap screws on the right and the original Specialized ones on the left. Even with my ropey photography it's pretty obvious that the new bolt head containing the Allen key slot is much smaller on the original. The original Specialized socket cap screws are recessed as shown in the first photo which depicts a rusty bottom socket cap screw still in place. The top bolt has been removed but the slim spring washer is still in the recess. You can also see that the original socket cap screw is quite a snug fit in the recess.

I'm sure Specialized didn't just commission these socket cap screws especially for the 2010 Specialized Globe Vienna 01 Ladies Stepthrough bike and that other Specialzed models around the same year will also have had these fitted.

Here are the details of the items that utilise these 4x socket cap screws:-
