Black phosphate Class 10.9 steel coarse thread hex washer head flange bolts are high-strength fasteners designed for demanding applications. Here are some key uses and characteristics of these specialized bolts:

Common Applications

These bolts are frequently used in:

• Automotive and machinery assembly: The high strength and corrosion resistance make them ideal for vehicle frames, engines, and heavy equipment.
• Construction and structural connections: Their load-bearing capacity suits them for steel structure assembly and other high-stress building applications.
• Industrial equipment: The flange head design provides a larger bearing surface, making them useful for securing components in manufacturing machinery.

Key Features and Benefits

High Strength: As Class 10.9 fasteners, these bolts have a minimum tensile strength of 1040 MPa, making them suitable for applications prone to shocks and vibrations.

Corrosion Resistance: The black phosphate coating provides a layer of protection against rust and corrosion, extending the bolt's lifespan in various environments.

Integrated Washer: The flange under the head acts like a built-in washer, distributing the load over a larger surface area and potentially eliminating the need for a separate washer.
