Topfix is not generally recommended. If unavoidable or specified for a particular application a saddle/storm washer should be used and particular care taken in installation.
A 6.3mm diameter coarse thread just under the head stitches the top outer sheet of the composite panel to the head keeping the sheet and washer clamped together giving a typical ultimate resistance force of 1.4kN in normal applications.
See fastener specifications link below.
A minimum 45mm embedment is recommended for HT into timber.
See Composite panel selection chart below.
These fasteners have a minimum 500hr SST coating. Link below.
The length specified is the length of the fastener from under the head before moulding, Add approximately 8mm to the length of the fastener for the total length including the moulded head.
Use a purpose made screwgun for installation. Cordless drivers and drill drivers are ideal with torque set fairly high on a high speed and in driver mode. Please note: Impact drivers should not be used under any circumstance and automatically voids any warranties.
Figures throughout will be ultimate test results with no safety factors.
