Hi,
can anyone tell me what thread of these are? Cheers.

 

Just bring one to Your local hardware store?

 

If I had to guess I'd say 1/4X20.

 

Looks to be 1/4-20

 

Thanks guys, being in the UK we are all metric but imperial threads are available. The internet suppliers are easier here for this kind of stuff, cheers

 

Cool wrench

 

any auto parts store has a place to check threads. looks like license plate bolts

 

Dont loose it.

 

And you're sure they're not British Standard Witworth?

Nahhhh,
Auto parts stores and (at least over here) the hardware stores have the ability to check threads, as long as they're fairly common. You can actually buy a tool that measures threads and takes the guesswork out. Google should bring up lots of different options, not too expensive if you plan to get grease up to your elbows. Enjoy your bike!!

 

I have a set of those on my license plate, they're 1/4 20 thread.
