Product Description

Product Description

There are several types of expansion bolts available, including mechanical, and undercut anchors. Mechanical expansion bolts use a wedge or tapered shape to create a secure hold within the material. Undercut anchors use a special drilling technique to create a larger hole in the material, allowing the sleeve to expand even further for a stronger hold.
Expansion bolts are commonly used in construction and engineering applications where a secure hold is required. They are easy to install and can be used in a variety of materials, including concrete, brick, and stone.

Features:
- Material: Carbon Steel/Stainless Steel Optional
- Surface Finish: Black Oxide, Color Zinc Plated, Galvanized, etc.
- High tensile strength
- Strong seismic resistance
- Strong fixation: special threaded connectors
- Corrosion resistance and long service life
- Wide range of sizes for specific requirements
How to use expansion bolts?
1. Choose the correct size and type of expansion bolt for your project. Consider the load and thickness of the material you are installing it into.2. Mark the location where you want to install the expansion bolt. Ensure it is positioned correctly and will be able to bear the load.3. Drill a hole into the material using a drill bit that matches the diameter of the expansion bolt. The depth of the hole should correspond to the length of the bolt you are using.4. Remove any debris from the hole by using a brush or compressed air.5. Insert the expansion bolt into the hole, ensuring that the threaded portion is fully inside the material.6. Use a wrench or a spanner to tighten the nut on the expansion bolt. As you tighten the nut, the bolt will expand and grip the sides of the hole. Continue tightening the nut until it is secure and the expansion bolt feels firmly anchored in place.7. Verify that the expansion bolt is securely anchored by giving it a gentle tug or applying a small amount of pressure. It should hold firmly. Once the expansion bolt is securely installed, you can use it to attach the desired item by placing it over the bolt and securing it with a nut or washer.* Always refer to the specific instructions provided by the manufacturer of the expansion bolt you are using, as the installation process may vary between different models and brands.
