Black Iron F436 Washer

SKU :

The Black Iron F436 Washer is a flat washer that is frequently utilized in construction and structural applications due to its high-strength, low-alloy steel material that has been treated to improve its resistance to corrosion. This type of washer is commonly used with high-strength bolts and nuts in heavy-duty applications where a larger bearing surface is needed to evenly distribute the load and decrease the risk of fastener failure.

The F436 washer is manufactured to meet specific standards for material strength, dimensional accuracy, and hardness to ensure consistent performance and reliability. It is designed to withstand extreme conditions, such as high pressure and vibration, and is commonly used in applications such as bridges, towers, and heavy machinery.

Overall, the Black Iron F436 washer is an essential component for ensuring the structural integrity of many different types of projects. Its reliability and durability make it a popular choice among engineers and builders who need a high-quality fastener component that can withstand harsh environments and heavy loads.


The Black Iron F436 washer is a flat washer commonly used in construction and structural engineering. The washer is made from high-strength, low-alloy steel and has a black oxide coating that enhances its resistance to corrosion.

One of the main characteristics of the F436 washer is its high strength. This attribute is attributed to the specific type of steel that is utilized in its production, which is formulated to provide durability and strength. As a result, the F436 washer is able to withstand heavy loads and resist deformation under pressure.

Another vital property of the F436 washer is its resistance to corrosion. The black oxide coating that covers the washer provides additional protection against rust, which is especially crucial in high-humidity environments.

The F436 washer also boasts a larger bearing surface compared to standard flat washers, which helps distribute the load evenly and lowers the risk of fastener failure. In addition, the washer is manufactured with specific standards for dimensional accuracy, ensuring that it fits appropriately with high-strength bolts and nuts. Additionally, it is designed to have a specific hardness that balances strength and ductility, thereby preventing cracking or breaking under stress.

The Black Iron F436 washer is a reliable and durable fastener component used in many different construction projects. Its high strength, corrosion resistance, large bearing surface, precise dimensions, and suitable hardness make it a preferred choice for engineers and builders who require a high-quality fastener component that can withstand harsh environments and heavy loads.
