The A1779-10Z1 is an aerospace standard sheet spring nut (Tinnerman type / speed nut) used for quick and reliable fastening in aircraft structures and sheet metal assemblies. It is designed to clip onto thin panels or structural edges, providing a threaded locking point without the need for a permanently installed nutplate or access to the reverse side of the structure.

This type of nut is widely used in aircraft interior panels, access covers, fairings, and light structural assemblies where fast installation, vibration resistance, and weight savings are important. The spring steel design grips the panel securely and maintains tension on the fastener to resist loosening under vibration.

Manufactured from corrosion-resistant spring steel, it provides durable performance in aviation environments and is commonly used in both OEM assembly and maintenance applications. Supplied here in a 50-piece pack, it is suitable for MRO and production use.
