Features

•IT DOES NOT HAVE TO BE SEATED
•IT IS RE-USEABLE WITHOUT LOSS OF ABILITY
•ONLY A SPANNER IS REQUIRED FOR INSTALLATION.

How can this be?
The upper nut is threaded down the screw until the machined recess comes into contact with the tapered cone (which is off-set) of the lower nut. The lower nut is held stationary, either by being seated or held stationary with a spanner if not seated. A locking torque between the two nuts is induced. Not only is this a vertical force (up and down the thread) – installation torque, but also a horizontal force is induced by the off-set cone of the lower nut. The lower nut is pulled into the screw threads in one direction, while the upper nut is pulled in the opposite direction. Hardlock is thus held stationary by three locking forces.

Repeated usage does not reduce the locking ability of Hardlock nuts, nor will there be undue wear
on either of the nuts or the thread of the screw because of repeated removals and subsequent installations.

In vibration tests carried out by independent and recognised testing authorities, the Hardlock nut has shown itself to be superior in it's resistance of vibration to all the other normal thread locking devices.
