Installation Sequence
Installation Sequence
Stump Lockbolts Typical of LGPS18SC, LGPS2SP, LGPS4SC & LGPS4SP Fasteners
Step 1
The pin is inserted into the hole with a transition or interference fit from one side by the drill riveter machine. The collar is automatically feed to the pin and placed over the locking groove section.
Step 2
The swage anvil then moves into position and begins to develop clamp-up while swaging the collar. The pin is supported by the upper ram of the drill riveter machine during the swaging action
Step 3
Collar swage is complete when the drill riveter machine reaches the pre-set swage force. At this time clamp force has been generated due to the extrusion of the collar that creates a corresponding stretch of the pin. The retained clamp load developed is over 50% of the fastener ultimate tensile.
Step 4
The swage anvil is ejected by machine ejection force after collar is completely swaged. The installation is complete.
