Information about Flange Bolts

Flange bolts are a type of threaded fastener that consists of a hexagonal head (the flange) and a threaded shaft. They are designed to be used with a corresponding flange nut. The flange on the bolt's head serves several important purposes:

1. Distributing Load: The flange provides a larger bearing surface, which helps distribute the load or force applied to the bolt over a wider area. This can reduce the risk of damaging the material or surface being fastened.

2. Locking Feature: Flange bolts often have serrations or teeth on the underside of the flange. When tightened, these serrations bite into the material, creating a locking effect that helps prevent the bolt from loosening due to vibration or other factors.

3. Easy Installation: The flange also provides a convenient surface for holding and turning the bolt during installation, making it easier to tighten.

Flange bolts are commonly used in various applications, including automotive, construction, and machinery, where high-strength fasteners are required. They come in a range of sizes, materials, and finishes to suit different needs. Some flange bolts have a built-in washer under the flange, while others may have an integrated washer-like feature as part of the flange design.

When using flange bolts, it's important to follow proper torque specifications to ensure that they are tightened to the correct level of tension. Over-tightening can lead to damage or failure, while under-tightening can result in a loose connection. Additionally, it's crucial to choose the right material and finish for the specific application to prevent corrosion and ensure durability.
