Conical EPDM Sealing Washer - A4 Stainless 

Sealing washers have a spongy rubber material on the bottom surface to seal against both smooth and uneven surfaces.

The concave shaped stainless top washer maintains compressed tension when tightened between the fastening screw and work surface.

Gray EPDM material prevents against water leaking around the penetration of the screw into the material (a waterproof seal).

Most commonly used with Self Tapping Sheet Metal Screws and Self Drilling Screws

Material: A4 Stainless


A4 / 316 Stainless Steel fasteners are "marine grade" corrosion resistant; suitable for salt water applications. A4 fasteners also offer increased resistance to chemicals when compared with A2 stainless fasteners.


Commonly used in wet environments. Popular across a wide range of industries: automotive, agriculture, photographic, medical / surgical, food processing, robotics, architectural detailing, construction, HVAC, healthcare, sanitary, transportation, clean energy, etc
