Stripped ZERK fitting threads, Options?

[Tollster]

I have a stripped bushing shaft on my mower deck, and it seems as if all the zerks I have have minimal thread engagement. Do they make a larger diameter, or can I get a longer 1/4 28 thread zerk.
The shaft still has threads about .25" down and I do not wish to replace it if I have a cheaper route.
Thanks

They make both larger diameter and longer thread fittings. I'd try the longer threaded ones.
Napa or a farm store should have a selection. Harbor Freight has a stock of them in a kit for under 10 bucks.
