| DRIVING
STUD
High strength steel driving head can be used many
times over, and is suitable for use with power hammers.
COUPLING
Long length high copper alloy coupling counter bored
to completely enclose threads, protecting them from damage and corrosion.
Coupling is high strength and also corrosion resistant.
Driving stud to rod or rod to rod contact can be achieved
to ensure that the driving force is directly applied and the unique
hexagonal provides flats to enable easier tightening of the coupling
to the rod. If loosening does occur during driving however, the coupling
is strong enough to transfer the force whilst maintaining good electrical
contact.
ROD
99.9% pure electrolytic copper molecularly bonded
onto a steel core in accordance with national and international standards
to a thickness of 0.25mm. There is no metal interface, so dissimilar
metal reaction cannot occur and the copper cannot be separated from
the steel.
The core is low carbon steel of grade 080A20 or BS970
with a high tensile strength of at least 600N/mm2.
Threads are rolled onto the rod which ensures that
an even copper covering is maintained, even at the root of the thread.
Rolled threads are also give greater strength than
cut threads.
CLAMPS
High copper content alloy body, phosphor bronze screw.
Strong resistance to corrosion. Strength of screw enables it to be fully
tightened ensuring good electrical contact.
Just specifying a "copper
covered rod" can lead to problems. Specify "Furse" products by name
to be sure of a first class system.
