Product Description
The Heli-Coil NAS1130-02L15 (Heli-Coil Part Number: T3585-02C129) is a precision aerospace-grade screw-locking tangless wire thread insert designed to deliver foreign object damage (FOD) protection while securing male hardware against severe dynamic vibration. Precision-coiled from cold-drawn 304 stainless steel wire with a diamond cross-section, this tangless insert features internal locking coils with straight chordal segments that exert continuous prevailing torque onto mating threads. The advanced tangless design incorporates drive notches at both ends, enabling bi-directional installation without tang break-off or retrieval operations. Designed without external plating or dry lubricants, it builds permanent, wear-resistant threads in delicate assemblies while eliminating debris risks in critical defense, aviation, and electronics applications.
Internal Screw-Locking Profile Series of chordal locking coils apply continuous prevailing friction to hold mating hardware securely against heavy operational shock and dynamic vibration.
Tangless Foreign Object Damage (FOD) Prevention Replaces break-off tangs with drive notches at both ends, eliminating metallic debris risks and tang removal labor in sensitive components.
Bi-Directional Fast Installation Reversible profile allows non-destructive installation or removal from either direction without needing to orient or index the insert.
304 Stainless Steel ConstructionManufactured from work-hardened, corrosion-resistant steel wire to protect soft host materials against internal thread stripping, galling, and wear.
