FAQs

What does EPDM stand for?

EPDM stands for Ethylene Propylene Diene Monomer, a type of synthetic rubber known for its excellent durability, weather resistance, and flexibility.

What is A2 stainless steel?

A2 stainless steel is equivalent to 304 grade stainless steel. It offers good corrosion resistance and is suitable for a wide range of applications, including many outdoor environments.

Can I use these washers with standard screws?

These washers are specifically designed for use with self-drilling screws. Using them with standard screws may not provide the intended seal or performance.

What is the purpose of the black colour?

The black colour typically refers to the EPDM washer, which is often black. It does not affect the sealing performance but is a characteristic of the material used.

What is the temperature limit of the washer?

The BAZ washers have a temperature resistance of up to 180°C.

Are these washers suitable for marine environments?

While A2 stainless steel offers good corrosion resistance, for highly corrosive environments like marine settings, higher grades of stainless steel might be recommended. Consult specific project requirements.

How do I store these washers?

Store in a cool, dry place away from direct sunlight and harsh chemicals to maintain the integrity of the EPDM and stainless steel components.

Troubleshooting

Leaking after installation

Verify that the screw was adequately tightened to compress the washer, creating a seal. Check for any damage to the washer or screw during installation. Ensure the washer was correctly oriented.

Washer does not seal properly

Confirm the correct washer size is used for the screw and application. Ensure the screw head is not over-tightened, which can damage the EPDM. Check that the surface is clean and free of debris before installation.

Corrosion observed on the cap

While A2 stainless steel offers good resistance, extreme environments can still cause surface discoloration. Ensure the correct grade of stainless steel (A2) is suitable for the specific environmental conditions. Clean any surface residue.

Pros and Cons

Pros

  • Provides a reliable and long-lasting watertight seal.
  • Excellent resistance to corrosion due to A2 stainless steel.
  • Suitable for high-temperature applications.
  • Durable construction for demanding environments.
  • Specifically designed for efficient use with self-drilling screws.

Cons

  • Primarily suited for roofing and similar applications.
  • May be overkill for non-critical sealing tasks.
  • Installation requires appropriate tools for self-drilling screws.

Setup, Compatibility & Care

Setup:

BAZ washers are designed to be used with self-drilling screws. Ensure the screw size is appropriate for the material thickness and the washer's hole. The washer should be placed onto the screw before insertion. When the screw is driven, the EPDM washer compresses to form a seal.

Compatibility:

  • Material: Best used with self-drilling screws designed for metal or roofing applications.
  • Applications: Ideal for metal roofing, cladding, and other exterior construction projects requiring weatherproofing.
  • Temperature Range: Suitable for environments with ambient temperatures within the specified range, up to 180°C.

Care:

These washers are maintenance-free once installed. Their A2 stainless steel construction resists corrosion, and the EPDM is durable. No special care is required beyond ensuring they are properly installed to function as intended.
