Key features of stainless steel flanged hex head screws


Stainless steel flanged hex head screws, also known as flange bolts, are fasteners that combine the features of a hex head bolt with a built-in flange. The flange, a wide circular or hexagonal washer-like extension beneath the head, provides additional surface area and distributes the load over a larger area when the screw is tightened. This helps prevent damage to the surface being fastened and provides a more secure and stable connection.

Here are some key features of stainless steel flanged hex head screws:

1. Material: Flanged hex head screws are typically made from stainless steel, which offers excellent corrosion resistance, durability, and strength. The specific stainless steel grade may vary, but common choices include 304 stainless steel and 316 stainless steel for enhanced corrosion resistance in challenging environments.

2. Hex Head: The screw head is designed in a hexagonal shape, allowing for easy installation and tightening using a wrench or socket tool. The hex head provides a secure grip during installation and allows for higher torque application compared to other head types.

3. Flange: The built-in flange beneath the head provides a larger bearing surface and acts as a washer. This distributes the load over a broader area, reducing the risk of surface damage or indentation. The flange also helps resist loosening due to vibration and provides added stability to the fastened joint.

4. Threaded Shank: Flanged hex head screws have a threaded shank that allows them to engage with a threaded hole or nut, creating a secure connection. The threading can be fully or partially threaded, depending on the specific design and application requirements.

5. Applications: Stainless steel flanged hex head screws are commonly used in various applications that require a secure and durable fastening solution with corrosion resistance. They are widely used in industries such as automotive, construction, marine, and outdoor equipment. Common applications include machinery assembly, equipment installation, structural framing, and outdoor fixtures.

It's important to select the appropriate size, length, and stainless steel grade of the flanged hex head screw to suit the specific requirements of your application. Following proper installation procedures and torque specifications is crucial to ensure optimal performance and longevity of the fastened joint.
