High-Quality DIN 125 A / ISO 7089 Metric Flat Washers – Steel, Zinc Plated
Ensure the integrity and longevity of your mechanical assemblies with our premium-grade DIN 125 Form A metric flat washers. Manufactured from high-quality steel and finished with a durable, corrosion-resistant zinc plating, these washers are the industry standard for a vast range of industrial, automotive, construction, and electronics applications.
Designed to distribute the load of a threaded fastener and prevent damage to mating surfaces, our flat washers are an essential component for any secure bolted joint. They provide a smooth bearing surface that allows for consistent and reliable tightening, reducing the risk of loosening from vibration and extending the life of your equipment.
Key Features & Benefits:
-
Standardized for Reliability: Manufactured to the precise dimensional specifications of DIN 125 Form A and its superseding international standard, ISO 7089, guaranteeing a perfect fit and consistent quality for all your projects.
-
Superior Load Distribution: The wide bearing surface effectively spreads the clamping force from a bolt or nut, preventing surface marring, pull-through on soft materials, and stress concentration for a stronger, more durable connection.
-
Corrosion-Resistant Finish: Each washer features a high-quality zinc plating with a Trivalent Chromate (Cr+3) passivation. This finish provides excellent protection against rust and corrosion in indoor and moderate outdoor environments.
-
RoHS Compliant: Our zinc plating process is free of Hexavalent Chromium (Cr+6), making these washers fully RoHS compliant and safe for use in electronics, automotive, and other products destined for the global market.
-
High-Strength Steel Construction: Made from durable carbon steel with a standard hardness of 200 HV, these washers are designed to withstand high clamping forces without deforming, making them fully compatible with bolts up to property class 8.8.
