Special

The principle of Friction grip connection is to transmit applied axial loads by friction resistance of the connection interface, instead of bearing on bolt shanks.In achieving the superior strength characteristics of bolted structural joints, the idea of structural bolting is to develop the desirable joint friction by inducing high clamping force in the connection interface. This is achieved by properly tightening every structural bolts of the connection to specified tension.
