- Reduced maintenance costs through durable zinc-plated steel construction
Professional Applications & Engineering Value
These M8 zinc-plated steel flat washers deliver critical engineering solutions where vibration resistance and surface protection are paramount. The DIN 9021 certified design ensures uniform load distribution across M8 bolted connections in machinery, automotive assemblies, and structural frameworks. The zinc plating creates a sacrificial barrier against oxidation, significantly extending component life in humid or outdoor industrial settings. With precise 8.4mm inner diameter and 24mm outer diameter dimensions, these metric flat washers prevent fastener embedment and distribute clamping forces effectively across soft materials or painted surfaces. The Rockwell B56 hardness provides optimal balance between durability and flexibility, making them ideal for applications requiring repeated disassembly and reassembly without deformation.
Specification Summary & Compliance
Manufactured to DIN 9021 dimensional standards with precise Class A tolerance levels. Material specifications confirm zinc-plated steel construction with Rockwell B56 hardness rating. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, including the latest SVHC updates. Designed specifically for M8 screw sizes with 8.4mm inner diameter, 24mm outer diameter, and 1.8-2.2mm thickness range.
