A screwed connection comprises at least one rod end (10 12) with an external, thread (16) and a threaded sleeve (18) with an internal thread (20). The threaded sleeve (18) is screwed with axial play on to the rod end (10 12). A, cotter (26) is driven through a lateral opening (30) in the threaded sleeve (18) in, such a way that it bears on the threaded sleeve (18) and on the end face (22 24) of the rod end (10, 12) in order to press the external and internal threads, (16, 20) axially against each other. A screwed connection of this type is particularly suitable for the production of sleeve connections and end anchorages in the case of reinforcing rods with a rolled-on thread.

Why it's free to use
- Filed March 14, 2000. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 14, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 14, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
