Tool Selection and Single Action Installation Sequence
NOTE
3/16” Fasteners are color identified green on
pintail, shear cap or shear flange.
(1) During the initial. pat-t of the driving operation, the sleeve is
squeezed between the head of the pin and the nose of the rivet tool.
(2) The head of the pin upsets the sleeve to form a strong, bulbed
head on the blind side.
(3) When the blind head has been formed, the tool automatically
forces the locking collar (at the pintail end of the sleeve) into the conical
space between the recess in the head and the locking groove in the pin.
This
locks the parts together permanently,
(4) Pin is broken off in tension at the breakneck groove,
substantially flush with the head of the sleeve.
There is no projecting pin
left to be cut off in a separate operation.
