Welcome to Harbor Models Inc.
Need to adapt a shaft, threaded or smooth?
Here is your solution. Simply choose the female size and male size, "S" means smooth, "T" means threaded. If the size is not available in the dropdown menus use "C" and in the "Comments" section during checkout mention the size you need for each end and we'll make it happen.
Provided in water-resistant brass or stainless steel (depending on our current stock of material), either will be with a set screw on the female side (unless threaded).
Overall length: approximately 1-1/2" (3/4" of female and male)
Note: These adapters are made to order so please give us a few days to have these made up custom for you.
