The Unifix Washers EN ISO 7089 HV200 are precision-engineered hardware components designed for professionals and hobbyists who require reliable load distribution and structural integrity in heavy-duty assemblies. Featuring a bright zinc-plated (BZP) finish for enhanced corrosion resistance, these washers are ideal for industrial and construction projects where long-term durability against rust is essential. While they provide excellent stability, users should ensure they are selecting the correct metric sizing to match their specific bolt diameter to prevent potential loosening or assembly misalignment.

HV200 refers to the Vickers Pyramid Number, a measurement of the material's hardness. A 200HV rating indicates the steel is hardened sufficiently for standard heavy-duty industrial applications.
Yes, the bright zinc-plated finish provides good resistance to atmospheric corrosion, making them suitable for most outdoor projects.
No, these are zinc-plated carbon steel washers. They are distinct from stainless steel and offer a different balance of strength and cost.
These washers comply with the EN ISO 7089 standard, which defines the requirements for plain washers of normal series for general use.
Generally, no. They are ready to use as-is. Adding lubricant may change the torque-tension relationship of your assembly.
Verify that you are using the correct metric size washer for the bolt diameter.
Check if the zinc plating was scratched during installation and consider applying a cold-galvanizing spray.
Ensure that the torque applied does not exceed the mechanical limitations of the bolt and washer pairing.
To ensure optimal performance, verify that the washer's inner diameter matches your bolt size exactly. When assembling, ensure the washer is placed flat against the surface before tightening the nut. Do not use high-heat welding equipment directly on or near the zinc-plated finish, as the heat may damage the anti-corrosion coating. Periodic inspections are recommended for critical assemblies to ensure no hardware has loosened due to vibration. Keep the washers stored in a dry, low-humidity environment to maintain the integrity of the protective zinc coating until ready for use.
