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 316 stainless steel, 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.
