LIGNOLOC® Wooden Nails 4.7 | 58 mm

The LIGNOLOC® 4.7 × 58 mm wooden nail with head (item no. CN47AGWO-H.6) is the most compact wooden nail with head in BECK’s LIGNOLOC® range. With a length of 58 mm, it is specifically designed for thinner façade boards and lightweight panels – typically 18–25 mm thick face boards installed on a softwood substructure.

It is suitable for timber façades, privacy screens, garden sheds, garden pavilions, room dividers, and both interior and exterior applications. For thicker assemblies with face boards of 25 mm or more, LIGNOLOC® wooden nails with head are also available in lengths of 64 mm and 78 mm.

The 58 mm LIGNOLOC® wooden nail with head is the right choice when the required penetration depth into the supporting material – such as battens or counter-battens – is at least 30–35 mm and the façade boards are approximately 18–22 mm thick.

As a general design rule, the penetration depth into the supporting timber should be at least 1.5 to 2 times the thickness of the face board. However, the design values specified in the ETA and the project-specific structural design must always be taken into account.

For face boards thicker than 22 mm, the 64 mm or 78 mm LIGNOLOC® wooden nail with head is recommended. The free LIGNOLOC® design software by BECK provides a standards-compliant recommendation for each assembly.

Depending on the requirements, stainless-steel nails, façade screws, or metal-free wooden nails can be used for timber façades. The appropriate fastener depends on the wood species, façade construction, design requirements, durability specifications, and considerations relating to circularity and the building’s carbon footprint.

This is where the LIGNOLOC® system offers significant advantages over metal fasteners: wood remains wood, and no foreign material is introduced. Compared with metal nails, using LIGNOLOC® as a façade fastening solution can reduce CO₂ emissions by up to 66%.

The BECK LIGNOLOC® 4.7 × 58 mm wooden nail with head was specifically developed for visible fastening in timber façades. As a completely metal-free fastener, it is particularly suitable for façades made from larch, spruce, fir, and other wood species where corrosion staining or visible metal points are to be avoided.

Its wooden head blends harmoniously into the façade surface and enables a visually appealing fastening solution without visible metal components. Wooden nails can be sanded and coated together with the façade. In addition, compared with steel fasteners, LIGNOLOC® wooden nails reduce thermal bridging in the façade to an absolute minimum.

The 58 mm version is suitable for façade boards approximately 18–25 mm thick. For thicker façade assemblies, LIGNOLOC® wooden nails with head are also available in lengths of 64 mm and 78 mm.

The BECK LIGNOLOC® 4.7 × 58 mm wooden nail with head must be installed exclusively using the FASCO® F60 CN15-PS90-H LIGNOLOC® coil nailer.

This pneumatic tool is specifically configured for LIGNOLOC® wooden nails. Its air pressure, driving depth, and feed mechanism are designed for wood-based fasteners.

Standard coil nailers for steel nails are not suitable, as their different operating parameters may cause nail breakage, misfires, or incorrect driving depth. They may also invalidate the ETA approval of the connection.

For industrial automation applications, the HEAD CN15-PS90-H LIGNOLOC® nailing head is available as an alternative.

The BECK F60 LIGNOLOC® tool is compatible with all three lengths of LIGNOLOC® wooden nails with head: 58 mm, 64 mm, and 78 mm.

When the LIGNOLOC® wooden nail is driven using the pneumatic FASCO® nailer, intense friction generates heat at the tip of the nail. This activates the natural lignin in the wooden nail and creates a bonded connection between the nail and the surrounding wood fibres. This effect is known as lignin adhesion.

The resulting connection values for LIGNOLOC® wooden nails are documented in European Technical Assessment ETA-23-0041 for LIGNOLOC® wooden nails without head and ETA-23-0330 for LIGNOLOC® wooden nails with head. These values can be used for the structural design of timber-to-timber connections.

This provides planners and timber construction companies with a reliable basis for using LIGNOLOC® in professional timber construction projects.

Yes. The connection values for the LIGNOLOC® wooden nail with head are documented in European Technical Assessments ETA-23-0041 and ETA-23-0330 and can be used for the planning and structural design of timber-to-timber connections.

This gives planners, architects, and timber construction companies a certified basis for designing connections made with LIGNOLOC® wooden nails with head.

Structural design is based on the characteristic values contained in the ETA and on the applicable timber construction standards and regulations.

To support the selection of the appropriate nail length and project-specific design, BECK also provides technical manuals and digital design tools.

The BECK LIGNOLOC® wooden nail is made from highly compressed European beechwood.

The material is specially processed for use with the LIGNOLOC® nailing system and achieves the strength required for pneumatic installation into solid timber and wood-based materials.

Thanks to its wood-based material structure, the nail is completely metal-free and forms a homogeneous connection with the surrounding timber.

This creates a natural surface appearance and facilitates subsequent machining, including sanding, planing, and milling.

The material consistency of the wooden nail also supports circular construction with timber modules, as no foreign materials are introduced into solid timber elements such as cross-laminated timber, dowel-laminated timber, or log walls.

The BECK LIGNOLOC® wooden nail with head reacts to moisture in a similar way to the surrounding timber.

Because the nail is made from compressed European beechwood, it integrates into the natural moisture behaviour of the timber structure.

When properly designed and installed in accordance with the applicable rules of timber construction, the LIGNOLOC® wooden nail is suitable for its intended use in both interior and exterior applications. LIGNOLOC® wooden nails with head are explicitly approved for use in façades under ETA-23-0330.

Unlike metal fasteners, they cannot cause corrosion-related discoloration or rust marks on the timber surface.

As with all timber components, appropriate structural wood-protection measures and the relevant service conditions must be taken into account to ensure the long-term performance of the connection.

Yes. Larch façades can be safely fastened using LIGNOLOC® wooden nails with head.

Because of its relatively high density and natural drying stresses, larch places increased demands on fastening technology.

The blunt anti-splitting tip of the LIGNOLOC® wooden nail with head reduces the risk of timber splitting during mechanical installation, including in dry, planed, and narrow façade boards.

Larch also contains natural substances that may react with metal screws or nails. As metal-free fasteners, LIGNOLOC® wooden nails with head are therefore particularly suitable for preventing corrosion-related discoloration or rust marks on the façade surface and maintaining an attractive appearance over the long term.

Yes. The visible nail head is an intentional design feature of this version.

The head of the LIGNOLOC® wooden nail provides a clean finish on the façade surface, prevents thin boards from pulling over the fastener, protects against moisture ingress, and provides a larger bearing surface.

Because the nail head is made from wood, it blends harmoniously into untreated, oiled, stained, or pre-greyed timber façades.

Unlike metal fasteners, it does not cause rust streaks or corrosion-related discoloration on the façade surface. The nails can also be sanded or coated together with the façade.

The BECK Fastening LIGNOLOC® wooden nail enables completely metal-free timber connections and supports circular construction concepts in modern timber construction, with CO₂ emissions reduced by up to 66% compared with metal fasteners.

Because no metal fasteners remain in the structure, the timber can be more easily processed, reused, recycled, or recovered for energy at the end of its service life.

A further advantage is that downstream processing operations such as sawing, milling, planing, or shredding can be performed without the risk of encountering concealed metal components.

This simplifies the deconstruction of timber structures and supports circular construction concepts designed to keep materials within the value cycle for as long as possible.

The LIGNOLOC® wooden nail therefore offers benefits not only in terms of installation and appearance, but also with regard to resource conservation and sustainable material cycles in timber construction.
