What is the lead time for a custom flange bolt order

For over two decades at Gangtong Zheli, I’ve listened to engineers and procurement managers describe their recurring nightmares. They talk about assemblies that loosen under vibration, leaks that appear out of nowhere, and the constant need for retightening. It was through solving these very problems that I developed a deep professional respect for the Flange Bolt. Many see it as just another fastener, but I see it as an engineered solution. So, what truly separates a Flange Bolt from a standard bolt? Let’s break it down from a practical perspective.

How Does the Integrated Design of a Flange Bolt Solve Common Loosening Issues

A standard bolt is a simple component a threaded rod with a head. It does its job but often requires additional elements like washers to distribute load and prevent sinking into soft materials. The fundamental innovation of a Flange Bolt is its integrated design. The bolt head features a circular, fixed flange that acts as a built-in, wide-area washer.

This isn't just a minor tweak it's a game-changer for stability. The wider bearing surface of the Flange Bolt distributes the clamping force over a much larger area. This drastically reduces the unit pressure on the joint surface, preventing damage and maintaining grip integrity. At Gangtong Zheli, we’ve observed that this single feature is the primary reason our clients switch, as it directly counters the primary pain point of joint failure.

What Are the Key Performance Parameters of a Gangtong Zheli Flange Bolt

To understand the superiority of a flange bolt, you need to look at the hard data. Let's compare a standard M10 bolt with an M10 Flange Bolt from the Gangtong Zheli portfolio.

• Integrated Flange Diameter: 24mm (compared to a standard washer at ~20mm)

• Bearing Surface Area: Approximately 450 mm² (a significant increase over the standard bolt-and-washer combo)

• Material Grade: Class 8.8, 10.9, and 12.9, catering to various strength requirements.

• Surface Finish: Zinc-nickel plating for superior corrosion resistance, a critical factor in harsh environments.

Here is a quick comparison table to illustrate the performance differences in a typical application

When Should You Absolutely Choose a Flange Bolt Over a Standard Alternative

Based on my 20 years of experience, you should seriously consider a Flange Bolt in these critical scenarios

• High-Vibration Environments: Automotive engines, heavy machinery, and structural frameworks. The integrated flange provides superior resistance to loosening.

• Soft Material Applications: When fastening into aluminum or plastic, the wide flange prevents the bolt head from embedding and losing clamp load.

• Space-Constrained Assemblies: The single-unit design can be easier to handle and install in tight spaces where fumbling with a separate washer is impractical.

• Leak-Prone Connections: In piping or fluid systems, the even pressure distribution helps create a more consistent and reliable seal, especially when used with a gasket.
