Reliable mechanical anchors for concrete, brick and hollow walls. Discover a wide range of expansion plugs and drive nails for fast, durable and safe installations.

What are mechanical fasteners and how do they work?

Mechanical fasteners are components used to securely connect materials in construction, industrial, and installation applications. This category includes expansion plugs, mounting nails, anchors, and other systems based on mechanical anchoring—without the need for adhesives or chemical bonding. Their action relies on friction, expansion, or interlocking mechanisms to achieve a solid hold.

Main advantages of using mechanical fasteners

• Versatility: suitable for concrete, brick, plasterboard, wood, and many other materials.

• Durability: resistant to dynamic loads, humidity, and outdoor conditions.

• Easy and quick installation: requires basic tools and no additional chemicals.

• Reusability: many systems allow safe disassembly without damaging the substrate.

Practical applications

Mechanical fasteners are essential in residential, commercial, and industrial construction. They are commonly used in mounting HVAC systems, electrical and plumbing installations, balustrades, wall elements, shelves, and technical infrastructure.

Comparison with alternatives

Compared to chemical anchors, mechanical fasteners offer faster installation without curing time or mess. They are ideal where immediate load-bearing capacity and ease of use are priorities.

How to choose the right mechanical fastener?

When selecting mechanical fasteners, consider the following:

• Substrate type: concrete, brick, plasterboard, or porous materials.

• Load type: static, dynamic, vertical, or horizontal.

• Environmental conditions: humidity, temperature, corrosion, UV exposure.

• Need for removability: permanent or temporary installation requirements.
