We have these custom made for us. To our knowledge, no one else has these in this size or to these specifications.
These chain ring bolts are styled like the bigger ones used on bicycles that have been making their way over to the folder world.
These are machined to 1/2 thousand tolerance and can be used as a stand off or handle scale bolt.
If you need more length, we suggest buying a couple Male parts and using a connector between them.
NOTE: Several sets are shown for clarity of illustration. You purchasing 10 MALE pieces of the size indicated above. You may need two sets for a knife handle, depending on your design.
