Are these Profile Design Aerobar bolts (M6x13mm, etc.) a custom part?
Am looking to replace all the rusted bolts on my Profile Design T2+ aerobars.
The .pdf manual came with a detailed list of the bolts used - there are a bunch of them. Unfortunately, when I google these bolts, I don't find anything corresponding to these bolts. Are these custom pieces from Profile Design? I was hoping they would be generic hardware fasteners that I could just buy online at a bolt dealer.
Some of the ones of interest:
M6 x 18mm mushroom cap BCP
M6 x 15 mushroom cap BCP
M6 x 13 flat head BCP
M6 x 25 flat head BCP
M6 x 18 flat head BCP
M6 x 38 flat head BCP
I'm not mechanically inclined at all, but I did figure out what the M6 x 25 means at least. Was hoping some of you folks who work with these on a semiregular basis could point me in the right direction to getting new ones if they aren't a custom part from Profile Design.

I would still try to contact Profile Design and see if they'll sell you a bolt kit. You could buy all those bolts from a place like McMaster, but they probably only sell boxes of 20 for each type of bolt. The costs would add up pretty quick.
As you probably figured out, M6 means 6 mm diameter. The other number is the length in mm. The other spec you need to know is whether these are fine or coarse pitch bolts. Get a good ruler and count the number of threads per 10 mm of bolt. If there are 10 threads, then it's coarse pitch (M6x1.0), if there are ~13 threads, then it's fine pitch (M6x0.75). If it's something else, then it may be some custom part (pretty unlikely for this application).

I've had good luck buying bolts on amazon, cheap to begin with and since I have prime - free shipping
got a picture of these bolts? or at least the pdf?
