BIRNS Millennium Nut & Washer Sets
BR and OR Nut/Washer Sets
Inboard Nut/Washer sets are recommended to secure bulkhead receptacles and double o-ring receptacles into the bulkhead and prevent loosening. Nut/Washer sets are made of Type 316 SS, designed specifically for use with BIRNS Millennium BRs and ORs, and now also feature new lock-wire holes for additional
security in high-vibration applications.
