No worries, Chad.

You might be able to find bolts with the same threading (M6) and head style (flat head, aka countersunk or CSK), but I don't know if you'd find them offered in the same lengths as the OE bolts (20mm and 30mm). Maybe more to the point, the bike is warranted as-sold...so non-spec/non-OE parts would put you in a dicey position if you wanted to make a related claim later. Those bolts are included in parts kit 437027 from your Trek dealer.

I did set the tool to 8nm which is the max, just ordered some PB bits and will look to see if I can find that bolt in stainless, seems to be lower quality than other bolts on the bike.

Spec on those is grade 12.9...stainless alloys are considerably lower strength than that...

Hi Carl, how do u fit the 7.2nm Seatpost wedge and what does the bolt tighten into, I don't see a thread in the wedge?
I am no doubt confused and this has been considered before!
I have trek sc 7.5 2013.

it goes into the frame here...


and the threaded portion is a barrel nut like this...


which you can see as the round detail on the side of these two wedges...

Ah, I've lost the barrel nut. All is now clear!
Is that a part available to buy or will I need to get a new wedge?
Thanks for your help, greatly appreciated.

it's not sold separately. you might be able to find a Trek dealer who has one of the older versions of the wedge left over from a warranty exchange (though as time goes by this is increasingly unlikely), and could scavenge the barrel nut from that. otherwise, the wedge PN is W311236.
