Rotho Blaas HBS8200 8mm x 200mm Carbon Steel + Zinc Plated Torx T40 Drive Flat Head Asymmetric "Umbrella" Thread Sharp 1 Cut Tip Countersunk Screw with Under-Head Ribs w/Bit (100/Pack)
SUPERIOR STRENGTH - Steel with superb yield and failure strength (fy,k = 1000 N/mm2). Very high torsional strength ftor,k for safer screwing.
STRUCTURAL APPLICATIONS - Approved for structural applications subject to stresses in any direction vs. the grain (a = 0° - 90°). Asymmetric “umbrella” threading for better timber pull-through.
DUCTILITY - The bending angle is 20° greater than standard, certified according to ETA-11/0030. Cyclical SEISMIC-REV tests according to EN 12512. Seismic performance tested according to EN 14592.
CHROMIUM (VI) FREE - Total absence of hexavalent chromium. Compliance with the strictest regulations governing chemical substances (SVHC). REACH information available.
Features
- HBS is the queen of wood screws. Certified for structural applications, it has a high wood penetration capacity and superior seismic performance.
- The extremely broad range includes a myriad of diameters and lengths.
- Among wood screws, choose HBS, the carpentry screw synonymous with guaranteed quality and completeness of range.
- Its superior strength makes HBS the preferred torx screw among carpenters.
- In carbon steel with bright zinc plated, it is designed for use with solid timber, glulam (Glued Laminated Timber), wood-based panels and high-density woods.
- The values are tested, certified and calculated also for application on CLT, Microllam® LVL panels and high-density woods.
- The asymmetric “umbrella” threading ensures better wood pull-through. The excellent resistance to failure and yielding of the steel (fy,k = 1000 N/mm2) and its very high torsional strength (ftor,k) make it extremely safe in the screwing stage.
- Versatile, its bending angle is 20° greater than standard, certified according to ETA 11/0030. Cyclical SEISMIC-REV tests carried out according to the EN 12512 standard. Seismic performance tested according to EN 14592 standard.
- HBS is approved for structural applications subject to stresses in any direction vs. the grain (a = 0° - 90°).
- HBS wood screws are applicable in service classes 1 and 2.
- They contain no traces of hexavalent chromium and are compliant with the strictest standards governing chemical substances (SVHC).
- REACH information is available.
