WellNut® are chloroprene-rubber inserts which can absorb vibration and noise.
The WellNut® also exhibits excellent electrical insulation properties and can provide a seal against liquids and gases. They are particulary suited for use in low pressure environments.

Standard Flange

Ideal for general purpose use, where dampening of vibration and shock is required.

Large Flange

Large flange feature increases the bearing surface for weaker and thinner materials.


Snap-In Feature allows part to be pre-attached to parent material. Ideal for assembly line use.


The metal sleeve provides a robust bearing area for the tightening screw, ensuring a consistent application torque.
