  • High Quality: Made of high-quality 304 stainless steel, sturdy, wear-resistant, rust-proof, and impact-resistant, which can effectively protect the internal parts and prolong the service life.
  • Drop-in Design: Our anchors feature a drop-in design,allowing for precise control of expansion rate and expansion range to meet different concrete elements and engineering requirements.
  • Safe and Reliable: It does not loosen easily and its reliable expansion control mechanism has undergone rigorous safety testing to ensure safe use.
  • Good Performance: This product features a heavy-duty anchoring system and internal thread, typically used in conjunction with machine screws, bolts, and screws to secure the fixing device to concrete and other masonry materials.
  • Cost Saving: Since expansion anchors are made of precast concrete elements, while the anchor itself is always in the concrete, the bolts you use to hold it in place can be removed and reused. Thus, it helps you save money.
