Abstract

See full text

Disclosed are several clamps and a method for installing the clamps through at least two work pieces from one side. The clamps include a shank, a spacer, a core bolt and an expander. The shank and expander are keyed to together with the expander engaged on the core bolt such that rotation of the core bolt can bulb the expander to form a clamp surface on the blind side of the work pieces. The shank and spacer are temporarily held apart until the expander is bulbed wherein the shank is allowed to enter the spacer to clamp the work pieces. Subsequent over torque of the core bolts fractures a weakened portion of the core bolt permitting removal of the clamps when desired.
