ABSTRACT:
The present invention discloses method and apparatus for connecting together two members having mating surfaces by means of a plurality of fasteners such that equal compression forces are exerted on the members along force lines normal to a common plane. To accomplish the foregoing objectives, a plurality of pins are carried by one member and pass through bores in the opposite member. The pins are longitudinally extended simultaneously with a common internal extending force and stops are affixed to the ends extending through the second member snugly against the surface thereof. Upon release of the common extending force, all the pins attempt to restore to their original positions with equal restorative forces being equal and opposite to the common extending force applied thereto.
