Thanks to the impregnation and subsequent compression of the beechwood, wood-destroying basidiomycetes have no destructive effect on the LignoLoc® nails. This characteristic has been confirmed in a long-term test conducted for us by the EPH wood technology development and test laboratory in Dresden.
LignoLoc® wooden nails are currently available in lengths of 55, 60 and 65 mm and a diameter of 3.7 mm. However, the BECK Fastener Group's Research & Development department is already investigating additional lengths and diameters.
In principle, yes. As described in Eurocode 5, table 8.2, attention must be paid to the density of the wood type when fastening wood using pin-shaped connectors. Only woods with a density less than 500 kg/m³ may be nailed without pre-drilling.
Yes. We recommend use of the FASCO F44 LignoLoc®, a tool designed specifically to meet the requirements of the wooden nail. The larger opening in the feed mechanism and the guide flaps are important for a perfect shooting result.
The projecting end can simply be knocked off from the side with a hammer. LignoLoc® nails will always be inserted as deep as the wood structure permits. If you fire the nail into a knot, it is compressed in the same way as a metal nail.
Thanks to the impregnation and subsequent compression of the beechwood, wood-destroying basidiomycetes have no destructive effect on the LignoLoc nails. This characteristic has been confirmed in a long-term test conducted for us by the EPH wood technology development and test laboratory in Dresden. Beech is the most suitable type of wood, because it grows particularly straight and has a high density.
According to Eurocode 5, an edge distance of 26 mm and a distance of 55 mm from the end grain should be maintained in the case of woods with a density less than 500 kg/m² and a thickness no less than 26 mm. The spacing between nails should be 100 mm. If several nails are inserted in a row, they should be offset slightly to prevent the wood from splitting.
The primary material for LignoLoc® nails has been used for many decades, also in outdoor applications. Numerous examples of this are available.
Thanks to the welding effect, the nail also bonds with the part to be fastened. The characteristic pull-through parameter is around 5.16 N/mm².
The deadline for approval is September 2019 by the SVA, Committee of Experts of the DIBt (German Institute of Construction Technology). The DIBt reserves the right to carry out further tests.
The appropriate technical approval still needs to be granted for this purpose.
