ABSTRACT:
A connection for preventing relative movement between coupled members in a clamped joint. The coupled members are connected across a shear member which transfers shear forces from one member to the other. Each coupled member has a roughened surface with a 500 to 1000 microinch arithmetic average finish providing protrusions which embed into the shear member and allow positive load transfer without slippage. This shear member is made of a material having a lower resistance to plastic deformation than either of the coupled members. Clamping of the joint provides the necessary force for embedding the roughened surface of the coupled members into the shear member. The simplicity and low cost of this connection makes it particularly useful for a wide variety of bolted assemblies.
