NAS1130-08L10D - Screw Threaded Insert by Helicoil Stanley Engineered Fastening

The Heli-Coil NAS1130-08L10D by Stanley Engineered Fastening is a high-performance, military-standard tangless screw-locking insert designed to establish incredibly strong and resilient internal threads in lightweight or soft parent materials. Precision-formed from high-quality 304 stainless steel wire with a diamond-shaped cross-section, this wire thread insert compensates for pitch and angle errors to optimize joint load distribution. Featuring a specialized screw-locking configuration, it incorporates one or more straight segments or chords on the coils that apply a positive self-locking torque to the male bolt, ensuring a vibration-proof assembly. Because it is completely tangless, this insert completely eliminates the need for tang break-off and retrieval, eliminating the risk of foreign object debris (FOD) and significantly accelerating manufacturing cycle times in critical aerospace, electronic, and defense systems.

Tangless Design Provides permanent, wear-resistant threads while completely eliminating the traditional need for tang break-off and retrieval, protecting critical systems from foreign object debris (FOD).

Screw-Locking Mechanism Delivers a resilient internal self-locking torque on the male member through one or more specialized chords on the insert coils to ensure a vibration-proof joint.

High Material Adaptability Seamlessly adjusts to the natural thermal expansion and contraction of the parent material to maintain a permanently anchored fit within the tapped hole.

Premium Wire Construction Features precision-formed, diamond-shaped wire that requires no staking, swaging, keying, locking, or interference fits during installation.
