Tang-Drive Thread Insert for Light Alloy Substrates

Product Description
 

Tang-Drive Thread Insert for Light Alloy Substrates

Restores 100% original thread strength in Al 7075-T6 / AZ91D Mg—where 1 stripped hole = $2,800 scrap cost (per 2025 IATF 16949 audit data).

Dual-Phase Reinforcement:

Hardened Carbon Steel (Grade 8.8) / 316L SS Options: 1,200 MPa shear strength (ISO 898-2) — 3.2× higher than parent aluminum (ASTM F606 tested).

Positive-Drive Tang System: Eliminates cross-threading during installation; achieves ±0.02mm positional accuracy (critical for fuel injector ports).

OEM-Validated Performance:

Torque Retention: 92% after 500 thermal cycles (-55°C to 150°C) — exceeds Boeing BAC5009-1 for engine components.

Fatigue Life: 1.2M cycles at 150 MPa stress (SAE J429 Class 8 equivalent) — 2.7× longer than helical inserts in vibration testing.

Zero-Scrap Installation: 0.3mm undercut design prevents base material galling; compatible with standard HeliCoil® tools (no retraining).

Industry Applications
 

Ideal where thread failure = safety recall (>$4M per incident):

Aerospace: Wing spar fittings, landing gear actuators — meets NASM8846 Class 3 for critical joints; FAA AC 43.13-1B compliant for in-situ repairs.

Automotive: EV battery chassis, turbocharger housings — withstands 50G vibration + 200°C exhaust heat (validated per Tesla MCA-2024 spec).

Heavy Machinery: Hydraulic valve blocks in excavators — IP69K-rated sealing against high-pressure fluid ingress (ISO 16280).

Electronics: Satellite antenna mounts, server rack frames —
