Expandable bolts are fasteners that achieve anchoring through a mechanical expansion principle. During installation, the bolt is subjected to force, causing the sleeve to expand and create a tight mechanical interlock with the hole wall, thus providing reliable tensile and shear load-bearing capacity. They are commonly used for the fixed installation of building curtain walls, equipment bases, pipe supports, and interior and exterior decorative structures.

FAQ
FAQ
Q: Can expansion bolts be used for hollow bricks or aerated concrete?
A: Standard expansion bolts are designed for solid, high-density substrates. For hollow bricks or low-density materials like aerated concrete, we highly recommend using our specialized anchors. Our technical team is available to help you select the most suitable solution.
Q: What precautions should be taken when installing expansion bolts?
A: Precise drilling and thorough hole cleaning are critical. The diameter and depth must match specifications exactly, and all dust must be removed to ensure a secure hold. Please refer to our detailed installation guidelines for step-by-step instructions.
Q: Can samples be provided for testing?
A: Yes, we strongly encourage it. We provide samples for testing so that you can verify the product quality and performance firsthand before making a bulk order.
