Hex Flange Bolt Stainless Steel Screws (Flanged Head) – Product Description

Hex Flange Bolts made from Stainless Steel 304 are widely used in industrial fastening applications where strength, corrosion resistance, and ease of installation are critical. The integrated flange under the hex head acts like a built-in washer, distributing load evenly and reducing the need for additional washers in assembly.

This type of fastener is commonly used in machinery, automotive components, construction structures, and equipment assemblies where vibration resistance and long-term durability are required.

Descripción general del producto

un Hex Flange Bolt Stainless Steel Screw is a one-piece fastener combining a standard hex head bolt with an integrated flange base. The flange increases the bearing surface, helping prevent loosening and surface damage during tightening.

Because it is made from acero inoxidable 304, it offers excellent resistance to rust, moisture, and many chemicals, making it suitable for both indoor and outdoor environments.

Key Specifications

Material Advantage – Stainless Steel 304

Stainless Steel 304 is one of the most commonly used austenitic stainless steels. It provides:

• Excellent corrosion resistance in normal atmospheric conditions
• Good strength and durability
• Resistance to oxidation and rust
• Suitable for general industrial and construction environments

It is not recommended for highly chloride-rich environments (such as seawater) where higher-grade stainless steel may be required.

Design Advantages of Flanged Hex Head

The flange design provides multiple benefits:

• Built-in washer effect → no extra washer required in most applications
• Improved load distribution → reduces damage to mating surfaces
• Better vibration resistance → helps prevent loosening
• Instalación más rápida → fewer components needed

Diseño de hilo

• Right-hand thread: standard tightening direction (clockwise)
• Coarse thread spacing: better resistance to stripping and faster assembly
• Fully threaded design: allows flexible grip length and strong fastening performance

Aplicaciones típicas

Hex Flange Bolts are widely used in:

• Automotive assemblies (engine parts, chassis connections)
• Maquinaria industrial
• Armarios electricos
• Conexiones de acero estructural
• Sistemas HVAC
• General equipment manufacturing

Frequently Asked Questions (FAQ)

1. What is the advantage of a flange head bolt?

The flange acts like an integrated washer, increasing load distribution and improving tightening stability while reducing parts required during assembly.

2. Is Stainless Steel 304 suitable for outdoor use?

Yes. Stainless Steel 304 is corrosion-resistant and suitable for most outdoor and humid environments, but not ideal for heavy saltwater exposure.

3. What does “fully threaded” mean?

It means the bolt has threads along the entire length of the shank, allowing flexible installation depth and strong holding capability.

4. What is coarse thread used for?

Coarse threads are commonly used for general-purpose fastening. They are faster to install and more resistant to damage compared to fine threads.

5. Can flange bolts replace standard hex bolts?

Yes, in most applications. However, in precision assemblies where separate washers or specific torque distribution is required, standard bolts may still be preferred.
