Expansion bolts are heavy-duty mechanical anchors used to securely fasten objects to solid materials like concrete, masonry, or stone. They function by expanding within the drilled hole as the bolt is tightened, creating a strong, vibration-resistant connection. Common types include wedge anchors, sleeve anchors, and drop-in anchors.
Expansion bolts are widely used in construction, structural steel connections, equipment mounting, and safety-critical applications. They are available in various sizes, materials (e.g., stainless steel, zinc-plated), and configurations to suit different load requirements and environmental conditions.
