In case someone else wonders, the correct torque value if your main stem bolt is silver is 16 Nm, confirmed by Brompton CS. Thanks
Perfect fit and good weight saving

ConsHigh cost
ProsWeight saving
This bolt was a perfect replacement for the Brompton original. In my opinion worth the price as it saves nearly nearly 2g per £1. Also highly corrosion resistant, although I don't believe the Ti bolts are stronger than the steel bolts they replace, contrary to popular opinion.

Thread Pitch

Hi. This is just the right length bolt for something else I intend to use it for. Could you tell me the thread pitch please?

This bolt uses standard M8 coarse pitch which is 1.25mm.

Which Part Of The Brompton Does This Fit, Please?

Hi, if you fold the stem down you will see the bolt that fits into the headset, this bolt is a replacement for that. Regards
