Tension control bolts (TCBs), are a type of high-grade bolt that can be preloaded by a tightening process that is carried out entirely at the threaded end (i.e. at the nut or spline end) of the bolt. Consequently, TCB's are usually distinguished by their round heads (rather than hexagonal heads) and splines.
