How Lanfranco Slotted Locknuts Work
|
Locking feature obtained by the two self-locking slots found on the turret portion of the nut.
Each slot is de-pitched using precision manufacturing techniques. |

|
When installed, the turret regains its original form and each slot grips the flank
of the bolt thread on two different planes and opposite sides.
This form of locking does not damage the bolt and provides high reusability. Resistance to vibration has been confirmed by comparative tests carried out by CETIM Test Labs. |

The single piece all metal design ensures nuts will perform in temperatures of
-200oC to +400oC.
The ERM nut also has a captive disc spring washer. This one piece assembly is a time saver and guarantees bolt tension under any condition. |
