In the world of structural steel construction, every component plays a critical role in ensuring long-term safety, strength, and stability. At Coburn-Myers, we understand that even small components like washers can make a big difference. That’s why we proudly supply ASTM F436 hardened washers, a key element in high-strength bolted connections used across a wide range of structural applications.

What Are F436 Washers?

F436 washers are hardened flat washers specified by the ASTM F436 standard. Engineered to support the demands of heavy structural bolting, they are typically paired with high-strength bolts such as ASTM A325 and A490 in applications where load distribution and resistance to deformation are paramount.

Where Are They Used?

F436 washers are essential in:

• Bridge construction

• Commercial and industrial buildings

• Transmission towers

• Wind turbines

• Steel-to-steel structural joints

Whether the project is a multi-story commercial structure or critical infrastructure like a suspension bridge, F436 washers ensure that the structural bolts maintain proper tension and perform under extreme stress.

Key Benefits

At Coburn-Myers, our F436 washers meet or exceed industry standards and offer several advantages:

• High Hardness: Heat-treated for exceptional strength and resistance to wear.

• Load Distribution: Effectively spread the bolt load over a wider surface to prevent damage to connected materials.

• Durability: Designed to perform under dynamic loads without embedding or crushing.

• Corrosion Resistance: Available in a variety of finishes including plain, zinc-plated, and mechanically galvanized to suit different environmental conditions.

Types Offered

We stock F436 washers in both:

• Type 1: Made from carbon steel for general structural use.

• Type 3: Manufactured from weathering steel for superior performance in outdoor or corrosive environments.
