A standard BSW 5 вЃ„ 32 вЂі thread has a thread count of 32 threads per inch, not 24. The biggest problem with this thread is, that it is not actually a standard BSW thread. While metric threads and UNF threads share the same general thread shape, BSW threads have a different shape-the angle at which the thread grooves are cut is different. The British Standard Whitworth 5 вЃ„ 32 вЂіГ—24 thread has a diameter of (unsurprisingly) 5 вЃ„ 32 of an inch or 3.97mm and a 24 threads per inch - a thread pitch of 1.058mm. All this stuff can be looked up in another Wikipedia article. 32 threads per inch are equivalent to a thread pitch of 0.7938mm. Size #10 is just an arbitrary number defining a thread of diameter 0.19вЂі or 4.826mm. The UNF designation #10-32 describes a thread of size #10 with 32 threads per inch. Details on metric threads can be found in the relevant Wikipedia article.

The metric designation M5Г—0.8 simply means a thread with 5mm diameter and a thread pitch (the distance from the crest of one thread to the next) of 0.8mm.

To my knowledge it is not used in any razors, but it can be used as a replacement for both #10-32 and M5Г—0.8 threads.Дon't panic! I'll explain those thread numbers right away, without going into full blown thread theory - as interesting as it may be. This thread is known as BSW 5 вЃ„ 32 вЂіГ—24 and it's a lot of trouble and we'll come to that later. A smaller thread was used on 1914s, Gem Damaskeene, Gem 1912 travel sets and most lather catchers. This thread size was used for most 1912s, some 1924 type razors and Valet Autostrop razors. The Ever-Ready 1912 from above, for example, uses American #10-32 UNF threads. There are mainly two types of threads used on vintage razors. Different threadsДЄlas, modern and vintage razor heads and handles sadly do use different threads, so attaching a modern handle to a vintage razor head is not straightforward. You can make a grub screw yourself by taking a normal screw with the desired thread and cutting off the head. If they are black, they are probably made from carbon steel and will rust. If you buy grub screws to use with razors, make sure they are made from stainless steel or some other material that doesn't corrode. That way you can remove the grub screw should it ever disappear too far down the handle opening. If you ever screw a grub screw into a handle please make sure that the screw goes into the handle so that the hexagonal hole is still visible. You can use a fitting key or a small screwdriver inserted into this hole to turn the grub screw. Note, that one end of a grub screw has a hexagonal opening. My personal favourite is a British made Ever-Ready 1912 razor head paired with a modern 96mm stainless steel handle: Some of those razors benefit from being paired with a different handle. I love my vintage SE razors and some come with really nice handles, but most original handles are quite light and short.
