Abstract
A swage collar including a shank having a first end, a second end opposite the first end, and an outside diameter, a flange extending circumferentially from the first end of the shank and having a outer diameter, and a scalloped shoulder formed at a location where the first end of the shank transitions to the flange. When the swage collar is swaged, the shoulder is deformed from an undeformed state to a deformed state such that the shoulder is blended with the outside diameter of the shank and the outer diameter of the flange. When the shoulder is in its deformed state, it includes multiple curved portions each having a radius of curvature that visually indicates all around the outside diameter of the collar a complete swage of the collar. Knurling located on the outside diameter of the shank and proximate to the second end is deformable and provides a visual indication of the application of an installation tool.
