10 YearsAn expansion bolt (also known as an expansion anchor or mechanical anchor) is a fastening device used to attach objects to solid base materials such as concrete, brick, or stone. It consists of a bolt (threaded rod), an expansion sleeve, a nut, and usually a washer. When installed, the nut is tightened, causing the sleeve to expand against the walls of the pre-drilled hole, creating a strong mechanical interlock.
Excellent for heavy-duty applications and securing substantial loads.
Suitable for structural anchoring.
Works in various base materials (concrete, brick, block).
Available in multiple sizes and materials (steel, stainless steel, galvanized).
Creates a strong, vibration-resistant connection.
Resists pull-out forces effectively.
Made from durable materials with good corrosion resistance.
