Hexagonal flange bolts made of stainless steel are often used in applications that require high corrosion resistance, such as marine environments, chemical processing facilities, and other harsh conditions. The flat head of these bolts is wider than the bolt shank, which distributes the load over a larger mating surface, reducing the risk of damaging the fastened surface.
Features of stainless steel hexagonal flange bolts:
1. **Material**: Made of stainless steel (usually grade 304 or 316), it has excellent corrosion and rust resistance compared to ordinary steel.
2. **Head type**: The flat head design provides a larger contact area, which helps to distribute the tightening force more evenly and reduces the risk of damaging the fastened surface.
3. **Thread type**: Typically, these bolts come with UNC (unified coarse) or UNF (unified fine) threads, depending on the torque and strength required.
4. **Sizes and specifications**: A variety of sizes are available, including M2, M3, M4, M5, M6, M8, M10, M12, M16, M20, etc., and each size has specific length options.
5. **Thread Length**: Thread length can be short, medium, or long, depending on the requirements of the application.
6. **Nuts and Washers**: These bolts are usually supplied with matching nuts and washers to ensure safe and efficient assembly.
7. **Fastening Method**: Tightened using a wrench or electric screwdriver, and can also be used with washers for added stability and load distribution.
8. **Application**: Suitable for a wide range of applications including plumbing, HVAC, mechanical, construction, and general engineering where high durability and corrosion resistance are critical.
When purchasing stainless steel hex flange bolts, it is important to consider factors such as the specific grade of stainless steel, size and thread type, and required length to ensure they meet the needs of your project. Always check the manufacturer's specifications and certifications to guarantee quality and compatibility with your application.
