What is the size of the 4-allen bolts that hold the radio to the brackets on a 2013 ultra? Last time I had the fairing off I noticed one missing and forgot to check the size then.

Thanks in advance

 

Same as the inner fairing bracket bolts:
Harley Davidson 3061 SCREW, HEX SOCKET CAP SEMS, 1/4-20 UNRC.

I lost one installing the stereo this weekend, and stole from a bracket until i get one from the local dealer. 99c or so... finally a harley part i don't mind paying for! hehehe

 

Thanks for your help

 

happy to help. I think you can also grab one from a local HW store if it's 1/4-20. But for 99c i might just grab it at HD.

GL!
