Self-locking “AMECOIL” thread inserts.
|Amecoil locking thread inserts|
|AMECOIL develops, improves and expands its standard and SR thread inserts ranges, as well as its self-locking range.
This self-locking series corresponds in all points to the conventional series, the screw threads being locked by polygonal deformation of one or more turns of the thread.
This deformation results in a powerful locking on the sides of the screw thread and counteracts the unscrewing effects of dynamic stresses, vibrations and thermal loads. The locking torques obtained are comparable with the values indicated in standard ISO 2320.
The stainless steel self-locking thread insert is recognised by its red colour.
From +0.1 to +1 mm of the nominal diameter of the screw.
Performed using the AMECOIL tap.
… or those of the SR series, for even quicker installatio.
With the AMECOIL impact breaker or automatically.
