Do not know why the original broke

ConsLong winded to fit, no guidance on fitting on Brooks website
Lots of online methods of fitting.I used a G clamp to hold the inverted saddle to the workbench. I used a screwdriver to lever the bolt into the saddle nose. Then I used another G clamp to compress the metal saddle nose against the bolt.It had engaged when I undid the clamp.
An excellent screw

The tension adjustment screw broke on my B17. It took a bit of force and measured blows with a hammer to get the replacement into place, but it is now working properly and the saddle is restored to optimum performance. It was sagging without the tensioning screw. SJS are so useful for this type of spare part which is difficult to find for sale elsewhere.
