Important Information About Flange Bolts Pipe flange fittings made of copper, aluminum, and steel in China.

Those acquainted with flange bolts are aware of their diverse types, including hexagon flange bolts, national standard flange bolts, steam standard flange bolts, GB5787 flange bolts, GB16674 flange bolts, Q184 flange bolts, flange toothed bolts, hexagonal flange bolts, anti-slip tooth flange bolts, and various fasteners of different materials and specifications. Among these, the hexagon socket flange bolt stands out as the market's most prevalent and widely utilized flange bolt.

Usually, nuts are designed with a hexagonal surface for ease of use. In specific machine applications, the installation space for the nut may be limited, and the wrench space to tighten the nut can also be narrow. Hexagonal nuts allow for gradual tightening by turning the wrench 60 degrees, whereas square nuts require 90-degree turns each time.

Additionally, hexagon socket flange bolts can be utilized alongside bolts, screws, etc., to fasten machine parts securely. Furthermore, the hexagonal shape of the nut is designed to optimize material utilization.

Classification of flange bolts

50. Hexagonal head types include the flat head and the recessed head.
50. Surface color options include white plating, military green, yellow, and corrosion-resistant Dacromet, catering to various requirements.
50. Flange plate types vary based on the size requirements for flange bolt usage positions. These include flat-bottom and toothed plates, with the toothed variety serving an anti-skid function.
50. Depending on the stress mode of connection, there are two types of holes: ordinary and countersunk. Flange bolts for countersunk holes should match the hole size and are suitable for applications subjected to transverse forces.

Purpose of flange bolt

A flange bolt consists of a hexagon head and a flange plate, offering a larger "support area to stress area" ratio compared to ordinary bolts. This design enables it to withstand higher preload and exhibit superior anti-loosening performance, making it extensively utilized in automotive engines, heavy machinery, and other applications.

Advantages of flange bolts over ordinary bolts

Flange bolts stand apart from ordinary bolts. What advantages do they offer over conventional bolts? This is a question that many people have pondered. Allow me to provide a brief introduction on the matter.

Firstly, owing to their material characteristics, flange bolts exhibit high tensile, compressive, torsional, and shear strength. Typically, the bolt's head is thick and resistant to deformation. However, with standard bolts, vibration post-installation can lead to loosening, necessitating tedious re-tightening. In contrast, the thinner section of the flange bolt allows for slight deformation, resulting in a more secure locking mechanism.

Moreover, when it's time to tighten bolts in tight spaces, ordinary bolts may pose challenges due to their larger heads. However, with their smaller heads and the additional fastening provided by the flange plate, flange bolts allow specialized tools to access confined areas easily—a principle akin to that of hexagon socket bolts.

Furthermore, flange bolts boast corrosion and wear resistance, contributing to an extended service life. The flat pad atop the flange bolt provides added safety when used on softer or non-wear-resistant materials, minimizing the risk of perforation.
