KORREX® flat washer

Economical and effective

KORREX® flat washers made of white nylon are specially designed to distribute the pressure of a screw or nut over a larger surface. They have insulating properties and are resistant to all kinds of chemicals. Available in several sizes, these washers are an economical and effective solution in a variety of applications.

Chemical resistant

The nylon used to make these KORREX® flat washers is resistant to a wide range of chemical substances, including petrol, alcohol, seawater, acetone, acids, and many more.


Thanks to the elasticity of nylon, these washers absorb vibrations and noise better than metal washers. As a result, much less noise is generated. Unlike metal washers, they don’t rub on surfaces.
