Help Identifying these Grease/Oil Nipples?

[Symon]

Hey all,

So whilst I'm restoring my milling machine I've been meaning to ask about these grease/oil nipples. I'd like to identify them as they're not coming up in my searching.

Thought some of you guys could quickly identify the proper term for them

The cap basically twists to cover the hole.

Thanks in advance...I have faith
