Product Selection Differences for Flange Bolts

When selecting flange bolts, some key differences to consider include:

1. Material: Flange bolts are typically made of materials such as carbon steel, stainless steel, or alloy steel. The material chosen should be suitable for the specific application based on factors like corrosion resistance, strength requirements, and environmental conditions.

2. Coating/Finish: The coating or finish on flange bolts can impact their resistance to corrosion and wear. Common coatings include zinc plating, hot-dip galvanizing, and dacromet coating.

3. Strength Grade: Flange bolts are available in various strength grades, such as Grade 8.8, Grade 10.9, and Grade 12.9. The strength grade chosen should match the load requirements of the application.

4. Head Style: Flange bolts come in different head styles, such as hex flange bolts or serrated flange bolts. The head style chosen should be compatible with the application and the tools available for installation.

5. Flange Type: Flange bolts can have different types of flanges, such as serrated or smooth flanges. The type of flange can affect the anti-vibration properties and sealing capabilities of the bolt.

6. Size and Thread Pitch: Selecting the right size and thread pitch is crucial to ensure proper fit and functionality in the application. It's important to match the bolt size and thread pitch with the corresponding nuts and holes.

7. Certifications: Consider choosing flange bolts that meet industry standards and certifications, such as ASTM specifications or ISO standards, to ensure quality and compliance with regulations.

By considering these key differences when selecting flange bolts, you can choose the most suitable option for your specific application requirements.
