Fastener Lover ODM/OEM Customized Brass/Aluminum/Iron Flange Bolt

A flange bolt is a type of bolt that features an integrated flange or washer-like structure beneath its head. The flange serves multiple purposes, including providing a larger load-bearing surface, distributing the load more evenly, and acting as a built-in washer to prevent the bolt from sinking into the material.

Here are some key features and characteristics of flange bolts:

1. Head and Flange: Flange bolts have a typical hexagonal head like regular bolts, but with a wide circular or hexagonal flange beneath the head. The flange is larger in diameter compared to the bolt's shank and provides stability and support.

2. Integrated Washer: The flange of a flange bolt incorporates an integrated washer, eliminating the need for a separate washer during installation. This helps to evenly distribute the load and reduce the risk of loosening or damage to the material being fastened.

3. Non-Serrated or Serrated Flange: Flange bolts can have a smooth or serrated flange surface. Serrated flanges have small ridges or teeth that bite into the material, providing increased resistance to loosening caused by vibrations.

4. Different Bolt Types: Flange bolts are available in different bolt types, such as hex bolts (hexagon head), carriage bolts (rounded head with a square neck), or socket cap screws (hex socket head). The presence of a flange beneath the head distinguishes them as flange bolts.
