Passenger grab handle bolts - which size?

[Don T]

A quick question.

My bike was delivered from the factory without passenger grab handles.
I have now purchased a set of Holan Nomada panniers.
To mount the rack I need 4 bolts the same size as those that holds the passenger grab handles - what size is the bolts?

My guess is 40 mm long 10 mm bolts with a 1.25 thread..?

I ended up ordering OEM bolts and can confirm that you are correct ::008::
