Wanted: spare screw & barrel nut for Thomson seat post

Hello. I’ve lost one of the hex bolt screws and barrel nut to clamp my saddle to my Thomson seat post. The bolts and nuts from my other seat posts seem to be too wide (they look to be m5 size and the Thomson looks to be m4 width). I don’t suppose anyone has a spare (m4 size) hex bolt with corresponding barrel nut? Or any other hacks to suggest?

I’m in SE London and happy to cycle to you and exchange for a can of beer or two!

Thanks

Thanks. I saw those but was put off by the single review that said they didn’t fit! They had no dimensions in the product description- but if they’re genuine Thomson parts I hope they would.

Yes. That looks like it. As long as width of bolt is closer to 4mm than 5mm so it will fit. Happy to cover postage and beer money / forum donation. I can PM you.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
