Understanding Washer DIN 125 A 8.4 Specifications, Applications, and Importance

In the realm of mechanical engineering and manufacturing, one component often overlooked yet vital is the washer. Among various types of washers, the DIN 125 A 8.4 stands out for its specific design and utility. This article delves into the details surrounding the DIN 125 A 8.4 washer, exploring its specifications, applications, and the critical role it plays in engineering and construction projects.

What is a DIN 125 A 8.4 Washer?

The DIN 125 A 8.4 washer is categorized under the German standard (Deutsches Institut für Normung, or DIN) for flat washers. The “A” in its designation signifies that it is designed for general-purpose use. The numerical values indicate its dimensions the ‘8.4’ refers to the inner diameter of the washer, which is 8.4 mm. This size is suitable for bolts and screws of equivalent dimensions, ensuring a secure, load-bearing connection.

The washer is typically manufactured from various materials including steel, stainless steel, and plastic, with surface treatments such as zinc plating or black oxide to enhance corrosion resistance. The choice of material and treatment depends on the intended application and environmental conditions.

Specifications of DIN 125 A 8.4 Washer

Understanding the specifications of the DIN 125 A 8.4 washer is crucial for its effective application. Here are some key features

1. Inner Diameter 8.4 mm 2. Outer Diameter Typically around 14 mm (varies slightly based on thickness) 3. Thickness The thickness of the washer is usually standardized; various thickness options may be available depending on manufacturer specifications. 4. Material The most common materials used are carbon steel, stainless steel (like A2 and A4), and sometimes nylon for specific applications.

These specifications allow the washer to distribute loads effectively, preventing damage to the surfaces being joined.
