BOLT,5/16 CEI PK/25
A pack of 25 5/16 CEI (British fine-thread) bolts.
This is a 5/16 CEI bolt, sold as a pack of 25. CEI stands for Cycle Engineers Institute, the British thread standard used across a lot of vintage English motorcycle hardware, so this is a fine-thread bolt in the classic British size rather than a modern SAE or metric part.

Our catalog record on this one is brief - we don't have more detail on where specifically it's used or which model it was originally speced for. If you're restocking hardware on a British bike and need 5/16 CEI bolts in quantity, this pack covers that, but confirm the length and head style you need before ordering since that isn't spelled out in our records.
The alias WW04027 refers to the same physical part under a different catalog number, in case that's what's printed in your parts book.
