Expansion bolts are essential fasteners used in construction, manufacturing, and automation industries for securing objects to concrete, masonry, or other solid materials. These bolts expand when tightened, creating a strong and reliable hold. Common types include wedge anchors, sleeve anchors, drop-in anchors, and chemical anchors. They are widely used in machinery installation, structural support, and equipment mounting. Key features include high load-bearing capacity, corrosion resistance (often made of stainless steel or galvanized materials), and adaptability to various base materials. Expansion bolts ensure stability in heavy-duty applications, making them indispensable in industrial and commercial settings.
