Nathan K3 Mounting Bolt Size ?

Can Someone tell me what size they are ? I’m Thinking 1/2 Getting ready to Mount these Bad Boys!!!

Thanks Jake

I’m not sure, but try sticking 1/2" hose through the hole… That’ll confirm it :D.

yeah theyre 1/2" holes. i used 3/8" and washers, worked perfectly. felt unnecessary to use 4 1/2" bolts, because thats slight overkill

lol, i think anyone that upgraded to a k3 from a standard air horn has long passed that overkill category… myself included :wink:

Thanks Guys !!!
