Threadolet vs. weld boss vs. ?
(OP)
I have a question about terminology/naming of some branch connections I'm sure are very familiar to all of us. I'm also guessing that my company is not the only having experienced this problem.
The problem: receiving what Penn Machine (www.pennusa.com) calls a 'weld boss' in place of a 'threadolet' (www.bonneyforge.com). The 'weld boss' appears in real-life to have been machined from a forged coupling as the O.D.'s match for both fittings, and both coupling and 'weld boss' are made of the same materials, typically. The 'threadolet' (or sockolet) is made to the MSS-SP-97 standard.
An advantage of the 'weld boss' is a smaller required thru-hole in the run piping, and this is the advantage that we are after. (We have enough reinforcement in the wall of the 'weld boss'.)
My question: It appears that these 'weld bosses' have quite a few names. Is there a 'proper' name associated with an ASME, ANSI, or MSS-XX code for this beast? I am fighting a battle on a couple of fronts: our vendors are obviously confused, our shipping/receiving dept. needs some training on the differences, and we need to requisition them with some sort of standard methodology to consistently receive one or the other.
There are many different names for threadolets and the like as can be seen by comparing what McMaster, Grainger, and the other vendors/manufacturers mentioned above call the same item.

I do not understand your issue.
A Bonney Forge Thredolet and a Penn Machine Weld Boss look nothing alike.

Weld Boss example : htt
Are these the correct items??
A Penn Machine Threaded Outlet does look like a Bonney Forge Thredolet.

To find a solution to the problem it would be helpful to know to what part of the ASME code the weld bosses are manufactured and what that part of the code calls the weld boss. Our vendors obviously aren't guiding those workers that pull the stock off the shelves, and that is part of the problem. Either that, or the management at these vendors don't realize that these items are very different in reality and intention. In addition we need to do more policing on our end in receiving.
All of the solutions begin by calling the weld boss by the most appropriate name...and that is what I do not know. Aside I'm thinking of giving an O.D. of the fitting to deliniate one type from the other, and let the vendor figure out the best way for their stock pickers to obtain this information.

"Penn Machine Weld Boss or Equivalent"
You could even throw in a part number to make sure you're getting what you want. Then if someone wants to supply something different it's up to them to show you that their part is equivalent to the one specified.

Vendors seem to be getting harder to work with in several respects. I'm afraid that if I tie them to a brand name they won't see the forest for the trees so-to-speak.
I may try vpl's suggestion and see what happens.
