Been working on Speedex's lately and they have lots of grease zerks, a good thing, I guess. BUT, I started just taking them out and tossing aside and wanted to put new ones in, just in case old ones were plugged tight. Well, have a whole assortment of them in the 1/4-20? sizes, but each one goes in too far and hits the shafts and locks them up. Where they go into the tubes is just the thickness of the tube, no build-up or thicker part. I ended up putting the old zerks back into the holes then and greased them up and all were good. SO, where does one find short threaded zerks and what special name might they have to ask about? I bet if I ask locals they will look at me like I'm nuts or making this up. I have in past ground a groove in a shaft to clean the zerk when in, but I'm sure not gonna do all the ones on these rigs.
SHORT grease zerks?

I would try to find a machine shop supply house. You might have the drive in type , not the screw in type.
If you can not find the ones you need, you might have to grind off the end of the zerk.

They have threads, just not many. I've heard of the drive-in type, don't get how they stay in???? Would break off easy with a gun used on them? Might try grinding end off, but man, will be hard to hold and keep in a tool doing that I bet.

McMaster-Carr has the straight 1/4"-28 grease fittings available in two length threads.
The short-thread fittings are # 1095K41, The longer-thread fittings are # 1095K42.

They can be held in a good vise grip and held against the side of an emery wheel so your grinding with a flat surface. It don't take a lot, but be sure the hole is open when your done grinding.

I've also seen washers under them.
Yep, mine have washers on the steering spendles.

I found if I bought ones in Auto section they are shorter and work. The ones in the general hardware section or in parts drawers are the long tailed ones. Got them in and working fine now.
