Son has a camera mount for his bike which is attached via a "bolt" which tightens up.


New bolt with an Allen head, then carry an Allen key with him (it's

standard bike repair kit anyway).



This also avoid the problem with yet another spikey thing on your

handlebars, waiting for you to crash.

Thanks all - as usual, sensible suggestions on a different tack than I was thinking.

How do you measure the thread for something like this? It is a very narrow packed thread on the bolt itself.

I'd agree about the allen key fitting if it weren't for the fact that this is on the bike of a 12 year old who hasn't yet learned that taking tools with him is a good idea!

Most bikes are metric or UNF. Probably metric.

Measure shank dia and estimate threads per inch and look it up.

Heres something I found that might be useful
