This is a model of an NBW with the dimensions of, 1″ Bolt, 2″ Square Nut w/ 4″ Bell Washer in F-scale. These nbw’s are commonly used on the end beams of small rolling-stock cars to secure the truss-rods running under the frame of the car. They also can be used for metal tension rods in bridges and structures such as (sand and coal storage bins).
Note; All of my white metal casting parts are noted in F-scale (1:20.32) measurements. That being said, all or most, can also be used on any other Large Scale Model. If you need measurements of a part that may interest you confirmed, please contact me with your request.
I also design and run new molds for vendors, clubs and any special part or project you might be thinking about. Give me a call and we can talk about how we get it done.
