stud picture in useThe distinctive curved design of the steel roof from the 2012 Olympic Games Aquatic Centre utilised 20,000 TCB Studs as the design had not initially factored in access for the shear wrenches. Further, there were space limitations; angling a dome headed bolt through a hole requires several more mm clearance in the web; whereas TCB Studs were inserted from above or below to suit access and facilitate installation.

In the wind energy market TCB Studs have been incorporated into designs for leading tower manufacturers Siemens Gamesa and Lagerwey, and are also frequently used in high rise and rail applications.
