CAT 10 - roller button fittings

[PT3090]

I need to know if the grease fittings for the Cat 10 rollers are "standard" button head 3/8" NPTF or "Giant" buttonhead 3/8" NPTF fittings.
Which is correct?

Hi, I'm going through this myself right now for my Ten. The button heads are 7/8" button heads with 5/8-18 NF threads. I ordered 3/8 pipe threads and they are wrong. I have not found any yet with the correct threads. Hope this saves you some time. Maybe someone can help with this. catrjw@aol.com
