i don't need a continuous thread but at least 2" thread on each end. i found a shop near me that could do it but expensive for this type of thread.

RE: threaded rods
UNJF implies a sophisticated strength requirement. Do You need any of the following?
Rolled threads... or are cut threads OK (flight critical [fatigue] VS non-critical [static]?).
RH turn thru the length... or LH turn one end; RH turn opp end?
Alloy/strength? Carbon steel, LA steel, CRES? 95, 125, 140, 160, 180, etc -KSI?
Min weight design required? IE enlarged threads with a smaller diameter straight section blended-in-between?
Examples of what is available for aircraft [UNF not UNJF]
AN704 Tie-Rod Internal 3,400Lb (1/4-28)
NAS1454 Rod, Continuous Thread
Perhaps this concept would work better...
NAS363--369 Control Rod and Tube Assy 1/4-28UNF-3A Thread
Otherwise, You may be better-off designing what You need
