SELF-ALIGNING SLEEVED PROTRUDING HEAD FASTENERS WITH ELECTROMAGNETIC EFFECT PROTECTION FEATURES

摘要

A fastener system (10) for composite structure provides electromagnetic energy protection by incorporating a self-aligning head (SAH) fastener (12) having a head with a spherical engaging surface and a shank extending from the head for insertion through a hole in a composite structure and a self-aligning self sealing (SASS) washer (14) having a throat receiving the shank and a spherical mating surface interfacing with the spherical engaging surface of the head.
