Hi

My seatpost bolt is broken and i need to replace it, but i am unable to find this bolt anywhere

Its a M6 i think with the rounded head

I have tried with a M6x20mm bolt, but the head is too big and doesnt get into it


The bolt i am after is something like this https://trek.scene7.com/is/image/TrekBi ... ache=on,on


Any help?

Thanks

    Either try your local engineering shop

    OR

    Chuck the stock M6 bolt in a lathe and shave a bit off the head

    The bolt on my Trek seatpost mast snapped last night. Always tightened with a torque wrench below spec (7nm, ut never went past 6nm). They made of cheese or something?

    m6x20mm, these are cap head so probably small enough, and high tensile so far less snappable...

    I was assuming a standard M6 Socket Cap was too big. OP?
