Thanks for sharing!!!
You are doing good. As I explained in the post from the first link, it's better to refer to the clamp in type stems.... as 'bolt-in stems' (as you said you do) instead
of just 'metal stems'. Sounds like you have been doing correct. I don't see any need for terminology change really on your part as far as the clamp-in stems are concerned.
Some manufacturers do use the term Bolt-in to describe the clamp-in stems.
It's all in the 'metal stem" vs "rubber stem" terminology where it get's confused, especially with the TR600HP snap in stems, that have half of the internal brass tube exposed. People think this is the same or equivalent to a "metal" stem that others are referring to, which is the clamp-in style.
As stated, it's just not the laymen who are sometimes confused, it's kinda prevalent in the tire biz as many undertrained people don't know the proper terminology difference either.
As I explained to Ron below, even the snap in stems have a brass internal part, so they have metal too (which you can obviously see in a 600HP snap in stem since the protective rubber coating is only half way up the brass stem)
Suggest you check your tire valves stems
Here is a schematic of a TR413 snap in stem that people like to refer to as a "rubber stem". Note the internal brass tube that runs almost the length of the stem.
Maybe we can guide the terminology talk at least amongst ourselves when we read these type threads where members are using "rubber" and "metal" for valve stem terminology.
