find washer / Nut in Autodesk Advance steel API .NET

[official.jaydeo]

I want to create very custom BOM where objects with same attributes are Counted , I have been succeeded, in finding all the objects types such as Beams, Plates, BoltPatterns etc. but not able to do it with Washers and nuts

While Creating BOMs Manually you can find Washers and Nuts but not in API, 

Creating Manual BOM , is not an option as i want to sort them based on user attribute

This data needs to be obtained from the Steel Content databases.
