KingNut Mechanical Properties
The standard work material of the KINGNUT nuts is non-reinforced
Type 6.6 polyamide.
The following details refer to tests over a short period cunducted under normal
climatic conditions. In accordance with the guidelines of the general test
standards for plastics, the nuts were stored at least 24 h with test conditions
and before check at least 48 h after production.
23°C ambient temperature and 50 % rel. Air humidity conditioned.

KingNut Longtime Properties
The elastic-viscous properties of the material cause the mechanical
characteristic values to decrease during temporal load conditions.
The above short-term values should therefore be reduced accordingly.
On special customer's request more detailed information for
special applications can be given following simulation of the
load application by FEA (Finite Element Analysis). This applies
for both static (creep and relaxation tests) and dynamic considerations
(load change reactions, inherent frequency).
KingNut Conductivity
The KINGNUT nut is basically an electric non-conductor.
Volume resistance: 1E15 Ohm*cm
Surface resistance: 1E13 Ohm*cm
