Description: |
| This patent is in DATAMP only because of three related specialty wrench patents (D34,837, D34,838, and 680,560).
Those patents relate to specific features of this stay-bolt. Both the bolt and its cover plug have recessed key-wrench sockets, and the thimble is designed to be screwed into place, held on a wrench by the threads for the cover-plug. |
