HECO-UNIX-top floorboard screw - the quick and precise way
to lay wooden flooring The HECO-UNIX screw family is growing: The full-threaded screw with contraction effect is now available with a small raised head for use as a flooring screw. Thanks to its technical properties, floorboards can now be fastened quicker and with more precision than ever before.
T
he new thread design of the HECO-UNIX has more than proven its worth in the interior finishing sector. On insertion, the variable thread pitch pulls the boards together
despite the full thread, making it ideal for fastening floor boards. The HECO-UNIX draws the boards together and, at the same time secures them axially via the thread. This not only enables quick and cost- cutting assembly but also prevents the annoying creaking of the wooden flooring on the screw shank, also known as the “jacking effect”. Since the loads are transferred via the thread, the screw head is only required for inserting the screw with screwdrivers thus the very small head. The design of the screw also enables easier access with tight installation spaces within tongue and groove joints, as the screw won’t protrude into the adjacent board this also ensures precise fastening of profiled timber. In addition to the head and thread point the HECO-UNIX offers a further bonus when working with tongue and groove; the patented HECO-UNIX thread point reduces the risk of splitting the board, which means that it can be used in the thinnest of cross sections with small edge distances.
New applications in interior finishing Its new screw design makes the HECO-UNIX even
The new
HECO-UNIX- top floorboard screw ensures the precise fastening of profiled timbers
more versatile when used in the interior finishing sector. The possibilities range from the laying of floorboards and wood fibre boards on wood and the securing of an existing substructure to the fastening of skirting boards. In addition, the HECO-UNIX-top floorboard screw is also suitable for installing glazing beads in the hardwood window sector. The new floorboard screws are available in
diameters from 3.5mm to 4.5mm and in lengths from 40mm to 80mm, with a cosmetic bright zinc finish and anti-friction coating. The screws are supplied in the tried and tested HECO packages.
