A spin weld pin according the principles of the present invention can be rotated at a high speed relative to two or more framing members by a torque transmitting device. An axial force is applied to the pin as it rotates so that the pin contacts the framing members and generates frictional heat. The heat generated causes the framing members to enter a molten state and allows the pin to penetrate therethrough. Rotation of the pin is ceased and as the pin and framing members cool, a bond is formed that joins the framing members and pin together.
