Hex flange bolts come in two variants: one with a flat head and the other with a concave head. These bolts offer different surface color options, including white, military green, vibrant yellow, and a corrosion-resistant Dacromet finish.
The flange of these bolts varies in size and structure based on its placement requirements. Flanges can have either a flat bottom or toothed points, providing anti-slip properties for enhanced grip.
These bolts can be classified based on their connection methods as common or reamed hole types. The reamed hole flange bolts match specific hole sizes and are used when exposed to lateral forces.
To prevent loosening due to vibrations after installation, some bolts feature holes in the rods. Additionally, there are thin rod flange bolts that lack threaded rods, promoting flexibility in accommodating variable forces.
Steel structures often utilize special high-strength bolts that have larger heads and varied sizes to meet specific structural demands.

The selection of flange bolts isn't solely determined by a specific flange type but rather by the physical dimensions and bolthole configuration of the flange system itself. The size and grade of the bolt are crucial factors, with the grade indicating its strength; higher-grade bolts offer increased reliability, especially in high-pressure environments like steam lines that might demand grade eight bolts for optimal safety.
Flange bolts are versatile and compatible with various flange systems. Their sizes and strength ratings vary based on specific applications. Available in standard (e.g., 1/4 inch, 1/2 inch) and metric (e.g., 8mm, 10mm) measurements, these bolts are designed to ensure secure connections without slippage or loosening. They are a standard fixture across industrial applications where dependable connections are essential for efficient production processes.
