I recently bought a nightster, but the owner had the fender removed and couldn't locate the bolts. I'd like to put the fender back on, but I am not sure what the original bolts look like, let alone the actual size of them. Does anyone know, or know where I can look to find out? I am afraid the dealer would charge a lot for simple bolts.

Thanks!

 

5/16 - 18 (course thread) thread pitch.
Couldn't tell ya the length, but they're a button-head style. Get grade 8 bolts. You can buy 'em long and cut 'em to length (thread a nut on before cutting, it gives you something to hold on to while cutting and when you remove the nut it straightens the threads out). Do you have the hardware that goes along with the bolts? There's a suppport bracket for the back bolts. Don't forget the blue Loctite.
Check here for another bolt option:

If you paln on keeping the bike for a while get the parts manual. It has all the hardware listed in the back.

 

I should have mentioned that it's only the front fender. Is there still a support bracket?

 

Oh. Front fender.

Scuba, thanks so much. That photo really helps! I am going to go to Lowe's now and see if they have something close to this.
