The NietFullThings terrace screws with countersunk head made of stainless steel are excellent for all plastics, particle boards, and hardwoods (terrace construction). With the help of the wobble-free TORX drive and the high-quality sliding coating, screwing is child's play. The TX internal hex drive allows for easy and secure screwing from the start to the sinking of the screw. The stainless steel wood construction screws with cutting notch and peeling ribs are versatile and guarantee high resistance to environmental influences due to their INOX material. Official European Technical Approval ETA. To avoid splitting or other damage in hardwoods or thin profiles, NietFullThings recommends conducting an application test with countersunk screws. To determine the appropriate drill size, we recommend the following rule of thumb for maximum hold: screw diameter x 0.6. Example wood screw Ø6 mm x 0.6 = 3.6 ~3.5 mm drill to pre-drill. In most cases, you do not need to pre-drill.

• 1 suitable Torx bit included in the delivery. The V4A screws are more resistant and tougher than V2A screws due to their material. Professional DIYers can use the pan head stainless steel screws wherever strong environmental influences occur. The floor screws resist permanent moisture as well as the effects of acids and salts. V4A stainless steel screws are excellent for thermo, Itauba, oak, cedar, larch, Ipe, teak, Cumaru, and Sucupira wood.
• Technical Data (see Images): length (L) = 40 mm | Head diameter (dk) = 7.95 mm | Head height (k) = 3 mm | Drive = TX25 | Thread length (b) = 26 mm | Diameter (d) = 5 mm | Drive type = Inner hexagon | Thread type = Wood thread | Mold type = decorative head | tensile strength = 800 N/mm² | Material = v4a 1.4571 AISI 316 | corrosion resistance class (KWK) = 3 Torx Screws wood
• Areas of application: Due to their material, the V4A screw assortment is generally the right choice in rural areas, industrial zones, along highways, and in coastal regions. A high salt content in the air or chlorine from, for example, an open pool terrace, does not affect these robust stainless steel wood screws. These stainless steel wood screws are also resistant to tannin-rich woods, thus preventing rusty screw heads or rust streaks.
• For stainless steel terrace screws of class V4A, pre-drilling and countersinking is recommended. This procedure prevents splitting of the decking wood. Additionally, there are no slivers or splinters in the head area of the stainless steel screws; thus, the risk of injury is minimized. Furthermore, a test drilling should be carried out to determine how deep pre-drilling or countersinking needs to be done. The stainless steel wood screws can then be easily screwed in flush.
• The comprehensive range of countersunk screws makes it possible to choose between different material classes (C1, V2A, V4A), various lengths (40-80mm), and different quantities per package. Therefore, there are no limits to the flexibility in assembling your own wood screw Torx set. All of this is, of course, assembled and delivered in the usual high quality of niroxal and nietfullthings.
