Floor expansion bolts are fasteners used to secure objects to the floor.

It usually consists of bolts, expansion tubes, and nuts. Its working principle is to insert the bolt into the pre drilled hole, and then tighten the nut. At this time, the bolt will pull the expansion tube to expand in the hole, thereby firmly fixing it in the floor and providing reliable anchoring force.

Floor expansion bolts have the advantages of easy installation, strong load-bearing capacity, and firm fixation. Commonly used for fixing machinery, equipment, brackets, pipelines, etc. on the floor.

When selecting floor expansion bolts, it is necessary to consider factors such as the material of the floor (such as concrete, wood, etc.), the required load-bearing capacity, and the installation environment to ensure the selection of appropriate specifications and models of expansion bolts. During the installation process, it is necessary to follow the correct method to ensure that the depth and diameter of the borehole meet the requirements of the bolt, and to tighten the nut with moderate force to avoid excessive or insufficient tightening.

The selection of specifications for floor expansion bolts mainly considers the following factors:

1. Load bearing capacity: Firstly, it is necessary to clarify the weight of the fixed object and the potential dynamic loads that may be generated. Heavier objects require the selection of expansion bolts with larger diameters and lengths to provide sufficient support.

2. Floor material: Different floor materials, such as concrete, wood, etc., have different load-bearing capacities. Concrete floors are usually able to withstand high tensile forces, while for wooden floors, more careful selection may be necessary, such as choosing shorter but larger diameter expansion bolts to avoid wood cracking.

3. Installation space: Consider the space size of the installation location to ensure that the selected expansion bolt length is not too long and will not affect other components or structures.

4. Bolt diameter: Common diameters include 6mm, 8mm, 10mm, etc. In general, a smaller diameter can be chosen for light loads, while a larger diameter can be chosen for heavy loads.

5. Bolt length: The length should ensure that the expansion pipe can fully expand inside the floor and provide sufficient anchoring force, while not penetrating the floor. Usually, the bolt length should be slightly longer than the drilling depth to ensure sufficient thread allowance when tightening the nut.

For example, if fixing lightweight equipment on a concrete floor, 6mm diameter and 50mm long expansion bolts may be selected; For heavier machinery and equipment, expansion bolts with a diameter of 10mm and a length of 80mm may be required.
