Concrete nails Dedra CPX 27/20 — galvanized fastening nails for masonry and concrete

Dedra CPX 27/20 concrete nails are hardened, galvanized fastening nails engineered for secure anchoring in masonry and concrete. Designed for use where strong mechanical hold is required, these nails offer corrosion resistance thanks to their zinc coating and are intended for applications such as fixing timber battens, installing formwork and profiles, or attaching fixtures to brick and concrete surfaces. Their dimensions and hardened construction allow use with compatible pneumatic or manual nailing tools that accept CPX 27/20 size nails.

Advantages

The galvanized finish protects against rust and extends service life when used in indoor and certain outdoor environments. Hardened steel construction ensures reliable penetration and mechanical anchoring in dense substrates like concrete and brick. The nails are produced to consistent dimensions to provide predictable driving depth and holding performance when matched with appropriate tools and installation technique.

Suitable for

• Fixing timber battens and furring strips to concrete or masonry
• Securing formwork and metal profiles during construction
• Attaching fixtures, brackets or supports to brick and concrete walls
• Pneumatic or manual nailing tasks where CPX 27/20 size is compatible

Key specifications

• Material: hardened steel with zinc (galvanized) coating
• Intended substrate: concrete and masonry (brick, block)
• Design: straight fastening nail for mechanical anchoring
• Compatibility: suitable for nailing tools accepting CPX 27/20 dimensions

How to use

Select a nailing tool compatible with CPX 27/20 nails and confirm the tool settings for concrete or masonry applications. Position the workpiece against the concrete or brick surface, align the nail perpendicular to the substrate, and drive the nail until the head is seated flush or to the desired depth. For best results in very hard or reinforced concrete, pre-drilling or using specialist anchors may be required. Always follow the nailing tool manufacturer’s instructions and observe safe handling practices, including eye protection and hearing protection when using pneumatic equipment.

Usage recommendations

Use Dedra CPX 27/20 concrete nails indoors or in covered outdoor locations to minimize prolonged exposure to harsh weather. Verify substrate condition and load requirements before selecting mechanical fasteners; for structural or heavy-load connections consider engineered anchors or consult a structural professional.
