Product Details
- Made in Austria. Top European quality.
- Special thread geometry. Optimal traction in the end grain.
- Fastens wood to wood, even OSB panels. Screw without pre-drilling and pre-sinking.
- Fastens pressure-resistant insulation materials for on-rafter insulation. For insulation with a compressive stress above 50 kPa.
- Screwing permissible from 0° up to 90° to the grain. Fastens with all screw-in angles.
- The splitting effect in the timber is reduced through the special multi-stage head. Saves 50 % of storage, combines countersunk head and flat-head; transfers high forces, but can still be countersunk and facilitates screw connections close to the edge.
- Special ribs on the shaft and slip coating. Pre-drilling effect, easy rotation, battery-saving.
- SIHGA® tip. Fast setting of the screw, user-friendly and time-saving.
- Including SIHGAFIX®, Systemstift® and installation instructions. Time-saving, practical, precise, all accessories enclosed; SIHGAFIX® also enables screwing into deep grooves.
- SIHGA® Ornamental Washer MSZ for diameter 8 mm. This Ornamental Washer MSZ increases the tensile force of the head to 9.1 kN; very attractive solution.
- Screwing permissible from 0° up to 90° to the grain. Fastens with all screw-in angles.
- Design values. SIHGA® performs the calculation for you.

Greatest earthquake protection – GoFix MS II
- SIHGA® is ahead of its time.
Tests already under way for the latest revision of Eurocode 5. - Latest tests confirm excellent properties.
Ductility ensures safety. - Best ductility class S3 for earthquake resistance.
Safety according to prEN 14592. - Simulated earthquake load through cyclic bending of the bolts.
Reliable residual load capacity of at least 90 %.
GoFix® MS II application by means of impact screwdriver (Tested by the University of Innsbruck). Positive report for processing with impact screwdrivers.
GoFix® MS II using in end grain.
GoFix® MS II using in hardwood. Use in hardwood allowed.
Safety according to ETA -13/0842.
Head pull-through force and thread extension may be increased by the factor k; observe maximum tensile strength according to ETA. High load capacity for efficient connections.
Extensive application possible by means of pre-drilling.
In solid wood, glued plywood board and laminated veneer wood.
