That looks like standard "knurling" that just about any metal lathe operator should be able to do for you.

You could check around at some of the machine shops that work on regrinding engine valves or resurfacing motor heads.

If you can get brass rod in the diameter that you want most any machine shop should be able to whip it out in no time at all.

As for getting the rod you could be able to use brass welding rod or even steel or iron rod from the metal racks at the hardware store.

Some of the stuff the machinists have on hand might be more specialized than you want to pay for.


You could also just look for knurled knobs in the bins of screws and specialty fasteners at the big box hardware stores.

You will probably want to thread it on to stainless steel all thread rod with a backing nut to lock it in place.
