Hex Head Flange Bolts ASME B18.2.1: Engineered Strength for Secure Fastening

Hex head flange bolts ASME B18.2.1 are high-performance fasteners designed for demanding industrial and structural applications. These bolts feature a hexagonal head with an integrated flange, which distributes the load more evenly, eliminating the need for separate washers. Compliant with the ASME B18.2.1 standard, these bolts ensure uniformity, strength, and reliability across diverse engineering and construction projects.

Whether used in automotive assembly, machinery, or heavy-duty structural connections, hex head flange bolts ASME B18.2.1 offer outstanding performance, superior clamping force, and long-term durability.

What Are Hex Head Flange Bolts ASME B18.2.1?

Hex head flange bolts ASME B18.2.1 are precision-machined fasteners with a hexagonal head and a circular flange beneath the head. The flange acts as a built-in washer, spreading the clamping force over a larger area to reduce pressure on the material surface.

Key features of hex head flange bolts ASME B18.2.1 include:

• Compliance with ASME B18.2.1, ensuring dimensional accuracy and interchangeability

• Integrated flange for improved load distribution and vibration resistance

• Made from carbon steel, stainless steel, or alloy steel for enhanced strength

• Available in a variety of thread pitches, including coarse and fine thread options

• Offered in multiple surface finishes such as zinc plating, black oxide, or hot-dip galvanizing

The hex head flange bolts ASME B18.2.1 are commonly used where fast, reliable, and secure fastening is critical.

Advantages of Hex Head Flange Bolts ASME B18.2.1
