I'll try & describe what I'm after. Ordered a Garmin mount & Ram mount back plate, but need 4 x nut & bolts to attach these parts together. See below links for images of both parts. Anyone know what size nut & bolts I need? https://www.motardinn.com/motorcycl...sTO-BOXG_e78psZ97uQaAsm-EALw_wcB&gclsrc=aw.ds https://www.motardinn.com/motorcycl...8_reMcSEAuL0CqBIuQYaAlV7EALw_wcB&gclsrc=aw.ds
Never had this myself, but, I made a sat nav mount for my dad and used a ram mount. If I remember correctly I used M5 bolts to hold it onto my machined piece. I would suggest holding a rule over the hole and measuring it. Bolt sizes are per millimetre (standard metric coarse) so M4 is 4mm, M5 is 5mm etc etc. I would strongly advise you get Nyloc nuts for it, otherwise it may undo with vibration on the bike.
eBay or a local hardware store will be best bet. I may have a few in the garage too I can send out if you get stuck
