product information

SIHGA® tip
For perfect screw pattern, screw head in flush. For screw connections in hardwood WITHOUT drilling, we recommend GoFix® SH.
made in Austria
top European quality and added-value
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 wood 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
