what do you use as a factor for approximate weight of connection for steel members.

RE: factor of approx weight of connection for steel member?
I don't directly account for the weight of the connections I mean. If you were to compare the actual weight of the connections to the total weight of the member being connected, it's likely negligible

This is a question you should be asking some of your fabricating friends, or fabricators who have worked on your last few jobs. Different fabricators will have developed slightly different numbers for estimating lbs. of connection material/steel per ton of major materials involved on the job. This will also be highly dependant upon the type and complexity of the job. 14' deep plate girders and complex architecturally exposed steel details or trusses, etc. are just radically different in terms of gross tons of steel vs. connection costs. Probably more important than the lbs. of connection material is the estimator’s sharp eye as involves things like the complexity of the details, how well are the details and connections defined on the construction documents, how will are the connection loads shown, are they going to be responsible for the design of the connections, etc., etc. Keeping it clean and simple, on your part, will always buy you some more material, and save many fabrication hours and designing/detailing time on their part, and buy you a less expensive job. Ask some of those fabricators how each one of these types of things figures into the total cost. On large repetitive jobs, we would sometimes go back to the owner or EoR with our own (equal or better) detail, which was more amenable to our fab. methods and equipment set up, if we thought we could save them money, or make life easier for ourselves without any detriment to the quality of the finished project.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

As others have said, you should ask a fabricator. For general numbers you can get some information from RS Means and the like.
