Title:
MULTI-GRIP BLIND RIVET
Document Type and Number:
Japanese Patent JP2004069051
Kind Code:
A
Abstract:

To provide a multi-grip blind rivet available for workpieces having a wide variety of plate thickness and large size hole or slot.

A multi-grip blind rivet includes a rivet body 82, adapted to receive a portion of a mandrel 76. A plurality of indentations 88 are formed in an outer surface 86 of the rivet body 82 in each of three axially spaced trans-axial planes. Each indentation 88 is formed with a work hardened base surface 90 having a convex portion, which is formed with axially spaced first and second trans-axial edges 106 and 108 having nonlinear portions. Adjacent indentations 88 are separated by ribs 89. A flared intermediate surface 122 extends between the base surface 90 and the outer surface 86. The rivet 74 is assembled within aligned holes of workpieces, respectively, where, upon setting of the rivet, the indentations 88 collapse and the outer surface 86 bulges against walls of the holes to retain the workpieces together.
