Tongue-and-Groove Fasteners

The Hidden tongue-and-groove fasteners are developed for wide assortment of tongue and groove board with different parameters:  with various heights of to the bottom of the groove (3-11 mm  and depths of the bottom groove  flange (6-15 mm) . Boards are milled along the entire length on both sides at the factory or at the installation site with a manual milling cutter.

There are 3 group of Invitie grooved fasteners

  • for board with symmetrical groove

  • board with asymmetrical when the grooved board has upper flange longer than the bottom

  • for deck board of tongue and groove type as euro-batten and block house.

 

The Tongue-and-groove fasteners are also recommended for assembly of wooden decorative materials as  wood-polymer composite decking.

Tongue-and-groove fasteners for board with symmetrical groove

 

Tongue-and-groove fastenershave two and more equal groove wings connect two assembled boards;

- the fastener base has one and more GH holes for fixingtothejoist bar;

- the groove wings are of various lengths, enabling the  formation of   gap between the boards  from 2 to 18 mm;

- fastening wings are inserted into thegrooves of the board and connect the assembled boards;

- the fastener fixed on the joist bar reliably pressing the board to the joistthe wings;

 

Owing to the design and material the fasteners can adjust tochanges in the board geometry resulting from fluctuations of wood moisture from climate and temperature changes.
