I revel in the diversity of fasteners and thread systems that the British have produced, many originally designed for a different application, which may or may not have been necessary, but I applaud those engineers for thinking out of the box. The metric system is, well, “boring” comes to mind. I have enjoyed this thread as I have over the years marvelled not only at the diversity of thread systems but the diversity of manufacturers, and find it quaint but historically stimulating that they ornamented the bolt heads with their corporate names and symbols. It creates a picture the many little, and not so little, companies in the Midlands churning out fasteners (and a lot of the other sundry fittings on our cars) and driving (literally) the local and national economy.

So to answer your question... BEES was the vendor. The bolt you refer to with an actual Bee on the head is a very early bolt, and is one that I have in my collection.

The strength rating is "B" and the measurement is 28 to 35 tons per square inch or tons tensile. The range refers to "yield" strength and "ultimate tensile" strength as described in my attached article. FYI, multiply 28 or 35 times a ton and you'll get the strength in pounds, or psi...
