## Summary description

The ELKO-BIS 14mm washer is a specialized component designed for farmer screws used in roofing and facade installations. Featuring an EPDM rubber seal, it ensures a watertight connection and protects the surface from mechanical damage. This durable washer provides reliable sealing and corrosion resistance, making it an essential element for professional construction and metal sheet assembly.

## Long description

The ELKO-BIS 14mm EPDM washer is a high-quality sealing component specifically engineered for use with farmer screws in roofing and facade construction. This washer features a durable EPDM rubber seal bonded to a metal backing, providing a reliable barrier against moisture, dust, and environmental elements. It is designed to maintain its elasticity over time, ensuring that the connection remains watertight and secure even under varying weather conditions.
Advantages
The primary advantage of this washer is its superior sealing capability provided by the EPDM material, which is highly resistant to UV radiation, ozone, and extreme temperature fluctuations. By distributing pressure evenly across the surface, the washer prevents mechanical damage to the metal sheets during installation and helps to mitigate the risk of corrosion at the screw entry point. Its robust construction ensures long-term stability and performance in demanding outdoor environments.
Suitable for
Roofing installations using metal sheets
Facade cladding assembly
Securing metal profiles to wooden or metal substructures
Outdoor construction projects requiring weather-tight seals
When it may not be suitable
This washer is specifically designed for standard farmer screws and may not be compatible with specialized fasteners requiring different diameters or sealing profiles. It is not intended for high-temperature industrial applications where temperatures exceed the thermal limits of EPDM rubber.
Key specifications
Diameter: 14mm
Material: EPDM rubber with metal backing
Application: Roofing and facade screws
Weather resistance: UV and ozone resistant
How to use
To use the ELKO-BIS washer, place it onto the farmer screw before driving the screw through the material. Ensure the EPDM side is facing the surface of the metal sheet. Tighten the screw until the rubber seal is slightly compressed against the surface, creating a firm, watertight connection. Avoid over-tightening, as this may deform the washer or damage the seal.
What to consider before purchase
Verify the diameter of your existing screws to ensure compatibility with the 14mm washer.
Check the quantity required for your specific roofing or facade project.
Ensure the surface material is suitable for standard screw-based fastening.
Usage recommendations
For optimal performance and longevity, ensure that the metal surface is clean and free of debris before installation. Regularly inspect the screw connections after extreme weather events to ensure the integrity of the seal remains intact.
