For precise and fast series production of cross screw connections we recommend the professional installation aid. For easier screw-in, use screw-in assistance GoFix® ESH 8.
fastens blunt wood connections extremely quickly
transfers high tensile, compressive and shearing forces
made from hardened carbon steel
the permanent, secure and powerful fastening
screwing permissible from 0° up to 90° to the grain
fastens with all screw-in angles
SIHGA® drill bit
for stress-free, easy rotation, enables small edge and axial distances
pre-drilling also permitted, for GoFix® X+ Ø 6.5 mm with 4 mm, with Ø 8.0 mm with 5 mm, with Ø 10.0 mm with 6 mm
for renovating old timber or hard timber
stepless counter sinking screw head with deep, recessed drive
can be countersunk, without splitting effect in the wood and without the drive skipping out of the head
strengthens constructive wood construction
support reinforcements, anchor beams (combined bending girder), notches, transverse force reinforcements can therefore be produced quickly and individually
