The 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 clearance in the web; whereas TCB Studs can be inserted from above or below to suit access and facilitate installation.
In the wind energy market TCB Studs have been incorporated into new bolted shell tower designs for leading manufacturers Siemens Gamesa and Lagerwey, and TCB Studs are also frequently used in high rise and rail applications.
