Fastener Systems and Methods

A method of assembling a fastener system, wherein the fastener system comprises a washer, a nut, a retainer structure, and a gasket, wherein the washer comprises a bore extending between a distal end and a proximal end, wherein a first section of the bore extends from the distal end to a shoulder portion, wherein a second section of the bore extends from the shoulder portion to the proximal end, the method comprising:

• inserting the gasket in the second section of the bore of the washer, wherein the gasket is axially retained in the second section of the bore;
• inserting the nut in the first section of the bore of the washer;
• and
• coupling the retainer structure to the washer in the first section of the bore to axially retain the nut in the first section of the bore of the washer.

A fastener system comprising:

• a washer having a bore extending between a distal end and a proximal end;
• a gasket having a through-bore axially aligned with the bore of the washer, wherein the gasket is configured to be axially retained in the bore of the washer;
• a nut comprising bore having a threaded section and an unthreaded section, wherein the threaded section is configured to threadably engage a threaded shaft of a bolt;
• and
• a lock ring in the unthreaded section of the nut, wherein the lock ring comprises a threaded inner wall and an outer surface having a lug, wherein the lug is configured to rotatably lock the lock ring to the nut.
