Horn / driver interface

howard

I have a horn driver with steel threads and a horn with brass threads. Do I need thread tape or anything like then when I couple them together?

Wolf

The different metals would certainly give me a bit of pause before joining them.

Probably not, but ARP makes a thread sealer that is for sealing bolts in coolant passages but it works really well as a barrier in differing metals.

When replacing steel bolts in my aluminum motorcycle frame, I always use anti-seize. If you don't, they eventually become one.

Wolf

My dad and I use anti-seize on brake-slides as well as the rim mounts on wheels- easier to get off!

Kornbread

If you use anti-seize, be absolutely sure to get all of it off your hands before touching anything else. That stuff has a way of getting onto everything.

Anti-seize works well generally,but I suggested the ARP stuff because it won't back off the bolt tension with vibration. With Anti-seize the bolts could possibly work loose.

Wolf

Yep- gets everywhere!!

As soon as the bottle is open, it's on me. I have a love hate relationship with anti-seize.

...so true.
I can see the point in the ARP stuff, but any hardware/auto-parts store will have standard antiseize, which will work just fine. I use it on spark plugs every time, never had one work loose.

Brass is so inert that nothing is needed on your threads.
