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 Unlike threaded fasteners, the C50L HuckBolt delivers consistent installation results. High costs of calibrating, maintaining, and replacing tools are eliminated. Also, installation does not require expensive, highly experienced workers. Secure, Fast Installation 1 Swaged-on collar forms a permanent, vibration-proof connection. 2 Initial long length of fastener enables pull-out of large gaps. 3 Consistent, repeatable pre-load. 1 2 3 13 Howmet Fastening Systems
