Fastener Expansion Anchor Bolts Stainless Steel M16

Fastener Expanison Anchor Bolt is a type of fastener that is commonly used to attach objects to concrete or masonry surfaces. It is designed to provide a secure and reliable connection that can withstand heavy loads and lateral forces.


Expansion anchor bolts typically consist of a threaded bolt, a metal sleeve or tube, and a cone-shaped expander wedge. To install an expansion anchor bolt, a hole is drilled into the concrete or masonry surface and the sleeve is inserted into the hole. The threaded bolt is then inserted through the sleeve and tightened, which causes the expander wedge to push against the walls of the sleeve, expanding it and creating a secure hold.

Expansion anchor bolts come in a variety of sizes, materials, and configurations to suit different applications and load requirements. They are commonly used in construction, engineering, and manufacturing industries for securing structural steel, machinery, equipment, and other heavy objects to concrete or masonry surfaces.

What are Fastener Expansion Anchor Bolts used for?

Fastener expansion anchor bolts are commonly used in construction and engineering applications to secure and anchor objects to various types of materials, such as concrete, masonry, or other solid substrates. These bolts are designed to provide reliable and durable fastening solutions for heavy loads or applications where traditional screws or bolts may not be suitable.

Fastener expansion anchor bolts work by utilizing the mechanical principle of expansion. They typically consist of a bolt, an expansion mechanism (such as a sleeve, cone, or wedge), and a nut or washer. The bolt is inserted into a pre-drilled hole in the material to be anchored, and as the nut is tightened, the expansion mechanism is activated, causing it to expand and grip the surrounding material. This creates a secure connection that can withstand tension, shear, or other types of loads.

Fastener expansion anchor bolts are used in a wide range of applications, including but not limited to:

  1. Construction: They are commonly used to anchor structural elements such as steel columns, beams, and brackets to concrete or masonry surfaces.

  2. Electrical and plumbing installations: They are used to securely fasten conduit, pipes, or electrical boxes to walls, floors, or ceilings.

  3. HVAC (heating, ventilation, and air conditioning) systems: They are used to attach ductwork, supports, or equipment to building structures.

  4. Industrial equipment and machinery: They are used to anchor heavy machinery, equipment, or conveyors to factory floors or other solid surfaces.

  5. Fixtures and fittings: They are used to install shelves, brackets, or other fixtures to walls or ceilings.
