The Basic Classification Of Flange Bolts
Flange bolts are common fasteners widely used in highway and railway bridges, industrial and civil construction, cranes, excavators, and other heavy machinery. In many heavy-duty assemblies, flange bolts are preferred because of their strong clamping force and stable connection performance.
As a professional fastener supplier, Xinchi Fastener Company can supply a variety of flange bolts, including flange half thread bolts, hexagon flange nuts, flange all-metal lock nut insert type, flange wing nuts, and other related flange bolt and nut products. Xinchi Fastener Company would like to briefly introduce flange bolt types, hoping it will be helpful for selection and application.

Flange Bolts Classification – Types of Flange Bolts Explained
Flange bolts can be divided into several types based on structure and application. Each type has its own advantages in different engineering environments.
Hexagon head screw with holes (Flange Bolts with Safety Holes)
This type of flange bolt has pin holes on the bolt head. Metal wire can pass through the holes, which helps with tightening, prevents mechanical loosening, and improves anti-loosening reliability.
Hexagon head reamed hole bolts (Precision Flange Bolts)
These flange bolts with reamed holes are designed to better fix the relative position of connected parts and can withstand transverse shear and extrusion forces.
Cross groove concave hexagon head bolt (Light-duty Flange Bolts)
This type of flange bolt is easy to install and tighten. It is mainly used in light industry and instruments with small loads.
Square head bolt (Heavy-duty Flange Bolts)
The square head flange bolt has a larger head and force-bearing surface, making it easier for the wrench to grip. It provides convenient tightening and stable performance.
Countersunk bolt square neck (Flush Mount Flange Bolts)
This flange bolt has an anti-rotation function and is often used in applications requiring a flat or smooth surface after installation.
T-slot L bolt (T-slot Flange Bolts)
Suitable for single-side installation, the bolt is inserted into the T-slot and rotated 90 degrees so it cannot come out. It is widely used in compact structural assemblies.
Anchor bolts (Foundation Flange Bolts)
Anchor bolts are designed for embedded concrete foundations and are used to fix machinery and equipment bases. They are commonly used in structures requiring stable ground connection.
Steel grid bolts (High-strength Flange Bolts)
These high-strength flange bolts are mainly used in road and railway bridges, industrial buildings, towers, and cranes, offering strong load-bearing capacity.
