The small yellow croaker expansion bolt is a common type of expansion bolt, named after its resemblance to a small yellow croaker in appearance.

It usually consists of bolts, expansion tubes, and washers. When in use, insert the bolt into the pre drilled hole, then tighten the bolt to allow the expansion tube to expand inside the hole, thus achieving the tightening effect.

Small yellow croaker expansion bolts have the advantages of easy installation and strong load-bearing capacity. They are commonly used to fix lightweight objects to solid walls or ceilings, such as chandeliers, drying racks, towel racks, etc.

When installing the small yellow croaker expansion bolt, the following are some things to pay attention to:

1. Drilling size: Select a suitable drill bit for drilling according to the specifications of the small yellow croaker expansion bolt. The diameter and depth of the borehole should meet the requirements of the bolt, as being too large or too small can affect the fixing effect.

2. Substrate selection: It should be installed on a solid substrate, such as concrete, solid bricks, etc. Avoid installing on substrates with insufficient strength such as hollow bricks and lightweight partition boards, as they may not provide sufficient support.

3. Cleaning the hole: After drilling, the dust and debris inside the hole should be removed. Compressed air can be used to blow it clean or a brush can be used to clean it to ensure that the expansion bolt can fully expand and tightly bond with the substrate.

4. Bolt insertion depth: Ensure that the bolt is fully inserted into the hole and the expansion tube is fully inserted into the hole.

5. Tightening force: When tightening the bolt, moderate force should be applied to avoid excessive tightening that may damage the bolt or expansion tube, and it should not be tightened too loosely to avoid affecting the fixing effect.

6. Installation quantity: Based on the weight and size of the fixed object, reasonably determine the installation quantity and position of the small yellow croaker expansion bolts to evenly distribute the force.

7. Check the firmness: After installation, check the firmness of the bolts, gently shake the fixed object, and confirm that there is no looseness.

8.Environmental factors: Avoid installing in harsh environments such as humidity, high temperature, or chemical corrosion to avoid affecting the performance and service life of bolts.
