PRODUCT INTRODUCTION

Hex flange bolts are an essential product for any industry that requires powerful and reliable fasteners. These bolts have become increasingly popular in recent years due to their unique design and incredible strength. As the name suggests, hex flange bolts have a hexagonal head that features a flange at the base. This flange, which is wider than the head, provides a larger bearing surface for the nut or washer, making it easier to distribute the load and minimize the risk of damage to the surrounding material.

 

There are many different types of hex flange bolts available on the market, but the most popular type is the hex flange bolt with a serrated flange. This serrated flange helps to prevent loosening due to vibration or shock loads. It acts as a locking mechanism, providing extra grip and reducing the risk of the bolt backing out over time.

 

Another important aspect of hex flange bolts is the strength of the fastener. Hex flange bolts are commonly made from high-strength materials such as carbon steel, alloy steel, or stainless steel. These materials provide excellent corrosion resistance and are able to withstand high levels of tension and shear forces. The strength of the fastener is critical when it comes to ensuring the safety and reliability of the product.

 

In addition to their unique design and strength, hex flange bolts are also incredibly versatile. They can be used in a wide range of applications, including manufacturing, automotive, construction, and more. They are commonly used in structural applications where the integrity of the product is paramount, such as in steel fabrication or in the manufacture of heavy machinery. Hex flange bolts are also commonly used in applications where access can be difficult, such as in tight spaces, or where a high level of torque is required.

 

Finally, it's worth noting that hex flange bolts are easy to install and use. With a wide range of sizes and materials, merchants can offer their customers the right product for their needs. Hex flange bolts can be quickly installed using standard tools, and their unique design ensures that they remain secure and reliable over time.

 

In summary, hex flange bolts are a unique and powerful product that is designed to provide reliability, strength, and versatility in a wide range of applications. With their serrated flange design, high-strength materials, and ease of use, hex flange bolts are an essential product for any industry that requires a powerful and reliable fastening solution. When looking for a fastener that will provide the security and reliability needed in any application, look no further than hex flange bolts.

 

what is a flange bolt? Flange bolts are a common standard part, which is mainly composed of hexagon head and flange (the gasket under the hexagon is fixed with the hexagon) and the screw (cylinder with external thread). Bolts, which need to cooperate with nuts, are used to fasten parts connecting two through holes. Flange bolts do not require washers, thanks to the design of the flange, not only can be used as a washer, but also allow more areas to distribute the pressure evenly, so that there is no need to install other additional spare parts.

Types of Flange bolts

Flange bolts (flat head)

The flat-brain flange bolt is composed of a hexagonal head, a flange and a screw. The flat-brain flange bolt and the concave-brain flange bolt are basically the same except for the head. The screw can be fully or half-threaded according to the usage scenario. The size requirements of the flange are also different, divided into flat bottom and toothed, and the toothed can play a certain anti-skid effect.

Flange bolts (concave brain)

The concave-brain flange bolt is composed of a hexagonal head, a flange and a screw. The concave-brain flange bolt and the flat-brain flange bolt are basically the same except for the head. The screw can be fully threaded or half-threaded according to different usage scenarios. , and the flange can also be flat-bottomed or toothed according to the requirements of use, and the teeth can play a certain role in anti-skid.

Cross recessed flange bolts

The basic function of cross-recessed flange bolts is similar to other flange bolts, and the cross-recessed head can provide another loading and unloading method, which can improve the use efficiency in some usage scenarios.


What are the characteristics of flange bolts?


Due to its unique structure, the flange bolt is compared with other bolt connection methods in terms of connection. It has the advantages of convenient disassembly and convenient maintenance, increasing pre -tightening force to prevent loosening, and will not cause the advantages of phase change of the composition of the connection material. And carbon steel flange bolts made of carbon steel as raw materials can also withstand high stretching, compression, reversing, and shear strength, while stainless steel flange bolts made of stainless steel have excellent corrosion corrosion performance.

As an excellent Chinese flange bolt factory, we produced the flange bolts all use raw materials of well-known steel mills. In this regard, we can provide corresponding material reports. We can produce a wide range of flanges. , 10mm-3000mm we can be customized. For example, our common M6 flange bolts, M8 flange bolts, M10 flange bolts, 12mm flange snails, 13mm flange bolts, 14mm flange bolts, etc.

In addition, we has a reliable and stable surface treatment process, which can provide you with galvanized flange bolts and chrome flange bolts. High -quality surface treatment can provide good corrosion resistance, and at the same time, the toughness of the coating product will also be strengthened to make it more durable.
