Polypropylene (PP) flat washers are a great general use polymer washer and are commonly utilised in a wide range of applications. PP is one of the lightest materials we provide with a specific gravity of 0.9. This paired with excellent chemical and hydrolysis resistance and electrical insulation makes PP a great fastener for general use applications.
Polypropylene (PP) flat washers are compliant with DIN 125 specification and can be used in combination with an array of different material fasteners depending on application. Available in standard metric sizes (M4- M12).
