Lockbolts, Structural Blind Fasterners and Tooling

Insert pin into the prepared hole and the smooth bore collar is placed on the pin. 1 The installation tool is applied to the pintail. When the tool is activated, the jaws in the nose assembly pull on the pintail and the nose anvil pushes on the collar to remove any gap. 2 The nose anvil starts to swage the collar into the lockgrooves on the pin. Continued swaging causes the collar to lengthen and develop clamp. 3 When swaging of the collar into the lockgrooves is complete, the tool ejects the fastener and releases the puller to complete the sequence. 4 The C6L’s unique design virtually eliminates installation errors caused by operator or tool variables. The C6L ensures that once the collar swage is complete, the pintail breaks off and the fastener is tightly installed. No rework required. You can count on consistent, highly-uniform clamp force with every C6L installation, time after time. Secure, Fast Installation 1 Wide bearing collar and head spread load to ensure structural integrity. 2 Initial long length of fastener enables pull-out of large gaps. 3 Excellent gap pull-out and high retained clamp. 4 High-fatigue, annular lock groove form extends the life of your structure. 1 2 3 2 4 17 Howmet Fastening Systems
