    It's a grease nipple. Like the name suggests, it's for greasing that joint. A grease gun is the correct tool for the job. As you can see it has been serviced due to the grease oozing out.

    It looks like the zerk on the far side is missing.

    Q: What’s behind the nipple?

    A hole or passage way leading to the place that needs lubrication.

    A very handy device that allows one-way passage and to seal off unwanted contamination.

    So the oil nipples on my Myford ML7 lathe are the genuine Zerk pattern, as opposed to the ball ended grease nipples on other machines. Fascinating!

    Never assume that just because its a zerk that it needs grease!
