Standard:F436M
Description:
The F436M washer, also known as a hardened steel washer, is a specific type of washer designed for use with high-strength metric structural bolts. It conforms to the specifications outlined by the ASTM F436M standard.
Here are the details regarding the F436M washer with zinc plated or hot-dip galvanized (HDG) finish:
Size range: The F436M washer is available in a metric size range, typically specified in millimeters. The common size range for these washers is M12 to M100 in diameter, accommodating different sizes of metric structural bolts.
Finish options:
1.Zinc plated: Zinc plating involves applying a protective coating of zinc to the washer's surface. This finish provides corrosion resistance, enhancing the washer's durability and preventing rust formation. Zinc plated F436M washers are commonly used in various applications where moderate corrosion resistance is required.
2.Hot-dip galvanized (HDG): HDG is a process in which the washer is immersed in a bath of molten zinc, resulting in a thicker and more durable zinc coating than standard zinc plating. HDG provides excellent corrosion protection, making it suitable for applications exposed to harsh environments or outdoor conditions. HDG F436M washers are commonly used in applications where superior corrosion resistance is required.
Material: F436M washers are commonly made of hardened steel, which increases their strength and durability. The specific grade of steel used is typically medium carbon steel.
Function: The primary function of the F436M washer is to provide a large load-bearing surface under the head of a structural bolt. It helps distribute the load and protect the underlying material, reducing the risk of bolt failure and providing a more secure connection.
