Those push in types are in a lot of zerk kits. You need to check to see if the right size for your application is in the kit, but they are available

There is, and I have one; I got it from the local IH dealer probably 40 years ago.

A socket works just as well.

far as i know those are metric.

It will be ok. Find the right ones, use the right tool or equivalent.

Right one and a small socket. Or drill hole to take a more common larger one. Or drill it and tap it. Or drill it and weld a 1/4-28 nut on top.  
Actually don’t do that, it’s unsightly. But it would work. And be 10x better than the pics we see if parts on here that haven’t had ten pumps of grease…in 50 years

This is what I would recommend.  Tap in zerks are a stupid idea.  If they get ripped out, the old hole is not likely to hold a new zerk.

I’ve tapped the ones on the front spindles to 1/4-28, flat bottom tap, goes right in

Am i the only one that has ever drove a threaded zerk into a non threaded hole ?

Those are the only ones that’ll hold and not come out when you take the grease gun off of them.

Here i thought I might get flamed for admitting that I do that.🙃

Arent most zerks 1/16" NPT or 1/8" NPT unless they are metric. I was 75 years old before I found out that air tire valves are actually 1/16 NPT fittings from working with an 83 Ford 460 FI rail pressure sender for a fuel pressure gauge and Mcmaster has adapters to integrate them into a system.

Most everything I work with is either 1/8" NPT or 1/4" NF.

Thanks actually local Versatile dealer Mast has a quite of an assortment of stuff, was able to get the correct size , for the 3 point on the 856, used the old grease gun end to drive in, all is good, didnt know they were called King fisher, thought maybe grease zerks without threads?

Sounds like an excellent method for installation !

Usually I drill them out and tap to appropriate size. Occasionally will weld a 1/4-28 nut on if the material is thinner and there is a risk of the fitting bottoming out. Have run across some metric threaded fittings on some newer and Chinesium equipment.

For sure.  Kuhn has an obscure one, it’s like a metric course thread. I’ve not found a source for it anywhere, but from kuhn.  (mainly because I haven’t identified the pitch).
