I do not know if they all use the same fittings between brands, but specifically I have the Greddy and Omori brands. I am seeking the bolt and thread type they use for the output senders to oil pressure gauges etc. Also there is a big threaded hole for a plug Greddy uses which I need to plug as well. Problem is, I went to my local hardware store, and none of their plugs and/or bolts have the correct threading to fit. Is it a special compression thread or something that is hard to come by?

Pic showing the big gold plug that I need to fill as well as the oil cooler lines I need to plug up but cant find a bolt that fits:


Same goes for the Omori Unit. I need to find bolts that fit where the copper colored ones in the pic are located:

Those should be NPT: national pipe thread. 1/8" maybe. SHOULD is the operative word lol.

Actually, those are both Japanese products. So it is probably BSPT which is slightly different than NPT.

Know where I can get them locally?

Aw dang, Andrew you're right. Autometer has NPT to metric fittings, i'm pretty sure I've seen they also have NPT to BPT adapters.

Is it safe to assume that they probably use a banjo bolt that is BSP?
