Threaded inserts with locking keys

High-strength threaded inserts in AISI303 1.4305 stainless steel passivated. As standard they are available in metric coarse pitch, metric fine pitch, UNC-UNF and other materials and / or surface treatments on request.

They are in Free Running or Locking version, the self-locking version has a Dry-Lube surface treatment.

They have 2 or 4 locking keys which once positioned make the insert mechanically locked against unscrewing from rotation or vibrations. They are used to obtain high strength threads on different materials, from light alloys to steels or to repair damaged threads.

They can be installed in a simple way as the host thread is standard so it does not require the use of special taps, they can be removed and replaced if necessary.

The inserts are supplied with the locking keys already positioned inside the grooves. The pre-positioned keys ensure that by screwing the insert it automatically positions itself at the correct installation depth.
