Hi, I recently got one of those Tektro fork-mounted brake hangers for my canti brake.

The problem is that it's designed to be used with a fork drilled for a recessed nut. My fork just has a regular hole.

I know you can enlarge the hole with an 8mm drill bit, but I don't have access to a drill. Was thinking about getting a longer bolt, a nut, and a "curvy" washer.

Where do I find such things online? And what are the technical terms for them so I know what I'm looking for? Not sure what size/type/threads of bolt I actually need either....


Thanks!
