Specification Sorting Of Expansion Bolts

Expansion bolts are a commonly used type of connector, which have the characteristics of high strength and corrosion resistance, and are suitable for connecting various building structures. The specification table for expansion bolts is a parameter index of expansion bolt products, which includes information such as bolt diameter, length, tensile strength, and embedded depth, providing important reference for users to choose and use expansion bolts.

When rewriting the specification table for expansion bolts, we can sort them according to different indicators and continue writing based on actual application scenarios to meet user needs.

1, Sort by bolt diameter

The diameter of the bolt is a key parameter in the specification table of expansion bolts, which directly determines the bearing capacity of the bolt. Therefore, sorting by bolt diameter in the specification table is a common way.

1. M12 expansion bolt

The bolt diameter is 12mm and is suitable for connecting lightweight building structures, such as steel and wood structures, thin plate houses, etc.

2. M16 expansion bolt

The bolt diameter is 16mm, suitable for connecting medium-sized building structures, such as steel structures, frame structures, etc.

3. M20 expansion bolt

The bolt diameter is 20mm, suitable for connecting large building structures, such as high-rise buildings, bridges, etc.

4. M24 expansion bolt

The bolt diameter is 24mm, suitable for connecting super large building structures, such as large factories, elevated bridges, etc.

2, Ranked by tensile strength

In addition to bolt diameter, tensile strength is also an important parameter in the specification table of expansion bolts, which characterizes the mechanical properties of expansion bolts. Sorting by tensile strength in the specification table can help users select suitable expansion bolts.

4.8 level expansion bolt

The tensile strength is 400MPa, suitable for connection of light loads in light load structures.

8.8 grade expansion bolt

The tensile strength is 800MPa, suitable for normal load connections in general building structures.

3. Grade 10.9 expansion bolts

The tensile strength is 1000MPa, suitable for connections exceeding normal loads in large building structures and heavy-duty structures.

4. Grade 12.9 expansion bolts

The tensile strength is 1200MPa, suitable for connections with high performance requirements for expansion bolts in special engineering.

3, Sort by length

The length of expansion bolts is also an important parameter in the specification table of expansion bolts, which is related to the embedded depth and directly affects the bearing capacity of expansion bolts. Sorting by length in the specification table can make it more convenient for users to choose suitable expansion bolts.

1. Short expansion bolt

The bolt length is generally 50mm-100mm, suitable for shallow buried depth and light load connections.

2. Medium length expansion bolt

The bolt length is generally 100mm-150mm, suitable for connecting general building structures and general loads.

3. Long expansion bolt

The bolt length is generally 150mm-200mm, suitable for connecting large building structures and heavy-duty structures.

4, Sort by embedded depth

In addition to length, the embedded depth is also an important parameter in the specification table of expansion bolts, which determines the stress state of the expansion bolts. Sorting by pre embedded depth in the specification table can enable users to more accurately select suitable expansion bolts.

1. Expansion bolts with small embedded depth

The pre embedded depth is generally 4-5 times the bolt diameter, suitable for shallow buried depth and light load connections.

2. Medium embedded depth expansion bolts

The pre embedded depth is generally 5-7 times the bolt diameter, suitable for connecting general building structures and general loads.

3. Expansion bolts with large pre embedded depth

The pre embedded depth is generally 7-10 times the bolt diameter, suitable for connections in large building structures and heavy-duty structures.

In summary, the specification table for expansion bolts includes parameters such as bolt diameter, length, tensile strength, and embedded depth. By sorting them according to different parameters and continuing with practical application scenarios, it can better assist users in selecting suitable expansion bolts, ensuring the connection quality and safety of building structures.
