Expandable Diameter Fasteners

Expandable diameter fasteners are used in critical joints to adjust hole fill to desired levels of interference.

They are used in a variety of high vibration and high load transfer joints to provide superior alignment, reduce or eliminate relative movement and wear, and provide quick change capability. Among the many uses are helicopter rotor blade attachments, engine attachments, and external munitions attachments.

PCC designs and manufactures expandable diameter fasteners in pin, bolt, blind bolt, and special configurations to suit customer requirements.
