Friction grip bolt is also called. High strength friction grip bolt or HSFG. The fatigue strength of these bolts is more because of no stress concentrations in the holes which makes it suitable to withstand reversal of stresses.

Reversal of stresses refers to the situation where the direction of the applied load changes. In such cases, it is important to use bolts that can withstand the reversal of stresses without failing. The most suitable bolt for this purpose is the friction grip bolt.

Explanation:
Friction grip bolts are designed with a high degree of clamping force that is achieved by pre-tensioning the bolt before subjecting it to the applied load. This pre-tensioning creates a compressive force that counteracts the tensile force generated by the applied load. This means that the bolt is able to withstand both tensile and compressive stresses, making it suitable for use in situations where the direction of the load changes.

Other types of bolts such as black bolts and turned bolts are not suitable for reversal of stresses because they do not have the same degree of clamping force as friction grip bolts. They are also more prone to fatigue failure when subjected to repeated loading and unloading cycles.

In summary, the friction grip bolt is the most suitable bolt for reversal of stresses because of its ability to withstand both tensile and compressive stresses and its high degree of clamping force.
