ALT.STUD TR25W
An alternate-fitment mounting stud listed for the Triumph TR25W, also known as AA121C.
This is a stud listed for the TR25W, an alternate-fitment mounting stud in Triumph's own numbering. Our records on this one are thin - the catalog entry just gives us the part number and the model reference, without a figure title or extra detail to pin down exactly where on the engine it threads in.

The part is also known under the older AA121C designation, which is the legacy-format number for the same physical stud. If you're cross-referencing an old parts book against a newer one, these two numbers point to the same piece.
Give us a call before ordering if you want to confirm this is the right stud for what you're working on - with this little documentation on file we'd rather talk it through than have you guess.
