Abstract
Fasteners are inserted into a stack of members and terminated with parts having at least one of a dry dielectric coating and a dry dielectric seal at select locations to protect against electromagnetic effects (EME).
Claims4
A part for terminating a fastener, the part comprising:
- a fastener termination body including a washer having a central opening;
- and
- a dry dielectric coating on the fastener termination body, and a first dielectric seal partially covering the central opening at one of a distal and proximal location, the first dielectric seal secured to the fastener termination body, the dry dielectric coating and the first dielectric seal having a thickness and composition for inhibiting lightning current.
A part for terminating a fastener, the part comprising:
- a fastener termination body including a washer having a central opening;
- and
- a dry dielectric coating on the fastener termination body, and a first dielectric seal partially covering the central opening at an inner proximal location of the washer, the first dielectric seal secured to the fastener termination body, the dry dielectric coating and the first dielectric seal having a thickness and composition for inhibiting lightning current.
