RIVNUT (P/N 33-008-575-00-1) - New Surplus

The 33-008-575-00-1 is a blind threaded insert (rivnut) that installs machine-screw threads into thin aircraft structures from a single side. Manufactured in aluminum or steel per NAS1329/NAS1330 specifications, this fastener creates a permanent threaded boss without requiring access to the reverse side. Commonly used to attach interior panels, equipment brackets, and system components to airframe skins and thin-wall structures.

Installation uses a specialized rivnut tool to expand the insert, creating a secure mechanical lock. Verify thread size and grip depth match the parent material thickness before installation.
