One of the drawbolts on my SKS/Esge P45 fenders came off on the road. I don't want to pay $15 just to replace one little piece, so I found a regular bolt with the same width and thread, and tried drilling a hole through it. It must be harder than my drill bits, because it I didn't get very far. I think I'll look for a nylon bolt at the hardware store. Is there any reason that won't work?
