AYA FASTENERS Guide | What Are The Advantages Of Galvanized Flange Bolt?

Galvanized flange bolts are a variety of flange bolts that have undergone the process of galvanization, which helps increase the resistance and durability of the bolts. These flange bolts are excellent fasteners and provide stability when attaching two components. This article will walk you through the features of galvanized flange bolts, the advantages of galvanization, and the areas in which these bolts are commonly used.

 

Product Description of Galvanized Flange Bolt

 

 

Galvanized flange bolts are fasteners with an integrated washer-like flange head on one side. The other side has a threaded shaft. Then the flange bolt is coated with a zinc layer for galvanization. This design and process enhance the strength of the bolt to attach two components and withstand them.

Main features of Galvanized Flange Bolt

 

Galvanized flange bolts are available in various sizes and materials so that you can pick your choice based on your specific needs. The feature of a little head in the galvanized flange bolts helps provide maximum grip between the components.

 

 

Advantages of Galvanized Flange Bolt

 

Galvanized flange bolts are becoming more common than other types of bolts. There are several advantages to the galvanization process, which enhances the quality of these bolts. But before we get into the benefits, what is galvanization? This is a process of applying zinc coating to steel or iron — primarily to prevent rusting. Some of the benefits of Galvanization and Galvanized Flange bolts are:

 

Protection

Galvanized flanges have higher corrosion resistance. Therefore, it proves to be an excellent material even when the climate is extreme.

 

Durability

The primary feature of resistance helps in increasing the lifecycle of the nuts. It adds to the physical durability of the bolts. Compared to other bolts made of uncoated carbon steel or ductile iron, the metallurgical bond between the zinc coat and actual steel provides them a perfect layer of protection, even in terms of physical damage.

 

Cost-effective

The affordability ratio of galvanized flange bolts is also higher. They prove to be an excellent alternative to stainless and chrome alloys and are cost-beneficial.

 

Superior strength

Because of their shape, Galvanized flange bolts provide superior strength to traditional nuts because they help evenly distribute the load across the surface area of the bolt’s head. This superior strength of these bolts, therefore, aids in preventing loosening over time.

 

Time

Since galvanized bolts' unique design eliminates the need for additional washers or nuts, the assembling time is significantly reduced.

 

 

Applications of Galvanized Flange Bolt

 

Since the galvanized flange bolts provide maximum grip and distribute equal weight across the bolt’s head, it is one of the preferable bolt varieties ideal for applications where vibrations or other factors cause loosening is observed. Besides, these galvanized flange bolts are corrosion-resistant and have less wear and tear when exposed to extreme temperatures. Thereby, they make for an excellent option for outdoor applications. Some of the other areas of applications include automotive and construction industries and in attaching exhaust systems to vehicles and securing pipes.
