Countersunk TCBs from Tension Control Bolts Ltd return the same preload values as a standard TCB assembly, however the length of a CSK TCB is measured from the top of the bolt, rather than the underside of the head.
Typical applications for CSK TCBs include:
Countersunk TCBs are increasingly being specified for high rise commercial offices. Particularly in city centre buildings where rental rates are charged at a premium.
The use of a countersunk bolt will generate extra floor space per bolt per connection per floor, cumulatively generating substantial additional revenue for landlords. Designed with the high rise market in mind, the new GSUL corner shear wrench is designed specifcially for use in narrow splice joints.
Many bridges have incorporated CSK TCBs especially box girder bridges.
As the CSK head does not protrude from the steelwork, CSK TCBs have been incorporated into a range of aircraft hangar doors.
