Al needs some help.
Al needs to find out what size the threads are on the zerk fitting into a solid drive shaft coupler. Thanks.

I think it is 1/4-28 I will verify tonight.

I too am pretty sure they are 1/4-28, especially since that is the most common size for zerks. I'm 99.9% but can't be positive without having one right in front of me.

I'm gunna have to say it's metric. I have a sae guage and it doesn't match any of them. The tap is 1/4 28 and you can see it's different. None of my dies fit it.

It seems you're both right.
The zerk on the SS coupler is metric. (cheesy Harbor Freight tap gauge shows 27? (it's the smallest one on there, just below 0.95)
But, the coupler hole seems to be a 1/4-28 thread.

I think the zerk is 1/16-27 tapered pipe thread and the coupler thread is 1/4-28
