Here is a Warner Electric RH lead screw and nut assy. Warner model is R-0505-0034. The ball nut is part 8105-448-013, model R-0505. For rod, lead is .200, diameter is .500, ball diameter is .125. The total lenght is app 17-1/2 inches long, threaded length is app 16 inches. One end has a machined end, about 1-1/2 inches long. 3/8"diameter then drops to 1/4" diameter, and it has a flat. End with flat is app 1" long. Not sure what the 0034 stands for, assume for the custom maching on the one end. Threaded rod is magnetic, so not sure of material. The nut is app 3" long, with a diameter of 1". Flange end is 2-1/2" diameter. This is new old stock. No original vendor packaging included, excpet for the plastic bag it was in. Near the end where it was machined, there's a bluish discoloration for about an inch. Not sure if from the machining process. No spec sheets included but I do have a basic spec sheet if you need more info. Free shipping via USPS or UPS Ground, depending on zip. If you need any more info or pics, let me know please. Thanks.
