AN-6 Bulkhead Lock Nut — Anodised Alloy

An anodised alloy lock nut for securing AN-6 (-6) bulkhead fittings to panels, firewalls, and bulkheads. The lock nut threads onto the bulkhead fitting from the reverse side of the panel, clamping the fitting securely in place and preventing rotation or pull-through under load. Required for installation of both the AN-6 straight and 90° bulkhead fittings — sold separately from the bulkhead fitting.

Sold individually — price per nut.
