Rotho Blaas VGZEVO7140 7mm x 140mm Carbon Steel + C4 EVO Coating Torx T30 Drive Symmetrical Coarse Thread Sharp 1 Cut Tip Cylindrical Head Full Thread Screw w/Bit (25/Pack)
C4 EVO COATING - 20 µm multilayer coating with a surface treatment of epoxy resin and aluminium flakes. No rust after 1440 hours of salt spray exposure, as per ISO 9227. Can be used in service class 3 outdoor applications and under class C4 atmospheric corrosion conditions.
AGGRESSIVE WOODS - Ideal for applications with woods containing tannin or treated with impregnating agents or other chemical processes.
TENSION - Deep thread and high resistance steel (fy,k = 1000 N/mm2) for excellent tensile performance.
STRUCTURAL APPLICATIONS - Approved for structural applications subject to stresses in any direction vs. the grain (a = 0° - 90°). Reduced minimum distances.
Features
- VGZ EVO is the wood screw with total thread for structural uses.
- It is the ideal connector for applications with woods containing tannin or treated with impregnating agents or other chemical processes, and guarantees excellent tensile performance.
- VGZ EVO wood screw, guarantee of quality and durability for structures exposed to atmospheric agents.
- The VGZ EVO screw is approved for structural applications subject to stresses in any direction vs. the grain (a = 0° - 90°).
- It is the ideal connector for the construction of outdoor structures and for fastening aggressive woods containing tannin, such as chestnut and oak. The deep thread and highly-resistant steel (fy,k = 1000 N/mm2) guarantee excellent tensile performance.
- The values are also tested, certified and calculated for CLT and high density woods such as Microllam® LVL.
- The minimum distances between one connector and the next are reduced. In carbon steel, the VGZ EVO wood screw features 20 µm multilayer C4 EVO coating with a surface treatment of epoxy resin and aluminium flakes, which showed no rust after 1440 hours of salt spray exposure testing according to ISO 9227.
- VGZ EVO is the ideal screw for use on wood-based panels, solid timber, glulam, high-density woods, aggressive woods and chemically-treated woods. Service classes 1, 2 and 3.
