The wood construction screw, made in Austria, combines the advantages of flat-head and counter-sunk head screws. The externally monitored ETA approval guarantees the stated values.
| SIHGA® – Feature | YOUR- Benefit |
| Fastens wood to wood up to 500mm, even OSB | Screw without pre-drilling and pre-sinking |
| Fastens pressure-resistant insulation materials for rafter insulation | Also for insulation with a compressive stress above 50 kPa |
| The splitting effect in the wood is reduced through the special multistage head | Saves 50 % of the storage, combines counter-sunk head and flat-head; transfers high forces, but can still be counter sunk and facilitates screw connections close to the edge |
| SC 3® / SC 7® coating | Significantly increased corrosion protection, paintable and even suitable for applications in corrosivity category C4-long or C5-medium |
| Special milling ribs on shaft and slip coating | Pre-drilling effect, easy rotation, battery-saving |
| SIHGA® screw bit | Fast attachment of the screw, processing-friendly and time-saving |
| Includes SIHGAFIX®, Systemstift® and installation instructions | time-saving, practical, precise, all accessories enclosed; SIHGAFIX® also screws into deep grooves |
| SIHGA® MSZ ornamental washer for diameter 8 mm | This ornamental washer MSZ increases the tensile force of the head to 9 kN; optically very beautiful and high tensile force |
| Positive assessment for processing with hammer screwdrivers | Saves time and provides safety, also when working above the head |
| ETA European Technical Approval with external monitoring issued | Trustworthy, externally monitored values provide certainty regarding the processing and rule out quality fluctuations |
| SIHGA® TIP | For perfect screw image, tighten head flush to surface |
