Lightweight Corrosion-Resistant Titanium Threaded Inserts
A titanium threaded insert is a critical component for ensuring screw joint strength and reliability, especially in aerospace, marine engineering, and advanced equipment manufacturing.
Compared to standard steel inserts, titanium alloy inserts offer remarkable weight reduction, exceptional corrosion resistance, and high strength, delivering stable performance even in extreme environments.
Why choose titanium threaded inserts
Titanium alloys feature low density, high strength, corrosion resistance, and non-magnetic properties.
- Titanium alloys have only about 60% of the density of steel, yet provide equal or even higher strength.
- Grade 5 titanium forms an inert oxide film in air, remaining stable in seawater, acidic, alkaline, or contaminated environments.
- Compared to stainless steel, titanium inserts can reduce weight by around 40%, benefiting industries such as aerospace, motorsports, and robotics where lightweight design is critical.
- They maintain strength and dimensional stability in high-temperature environments, ensuring long-term reliability.
These qualities allow titanium inserts to significantly reduce equipment weight, extend service life, and lower maintenance costs.
Popular product types
Self-tapping (Trisert) inserts
When working with substrates such as aluminum, magnesium, plastic, or thin carbon fiber sheets, the traditional three-step process—drilling, tapping, and installing bolts—can be time-consuming and may cause thread stripping due to inconsistent tapping quality.
Self-tapping titanium inserts give you a "one-step drive, instant lock” solution:
- No tapping required—multi-tooth cutting grooves on the outer wall allow direct installation into pre-drilled holes, eliminating the tapping process.
- Made from GR5 (Ti-6Al-4V) alloy with an exceptional strength-to-weight ratio, offering significantly higher pull-out strength and torque capacity than aluminum or stainless steel inserts.
- Roll-formed threads with optional DLC or TiN coating for superior wear resistance.
- "Key-lock” effect once teeth embed, ensuring stability even in high-vibration environments.
- Maintains dimensional stability in thin sheets or plastic parts with no risk of secondary deformation.
Available in sizes from M3 to M24, with lengths from 1D to 4D. Customization includes anodizing, color oxidation, wear-resistant coatings, and dedicated installation tool kits for OEM/ODM projects. Quick Quote
Helicoil / wire thread inserts
When threads are stripped, broken, or when strong threads are needed in soft substrates such as aluminum, magnesium, plastic, or wood, wire thread inserts are the fastest and most reliable solution.
- Titanium spring-wire structure locks instantly during assembly, with elastic preload for vibration and impact resistance.
- One-person installation for efficient assembly—no welding, no full-part replacement. Boosts repair efficiency by ≥ 50% and minimizes downtime.
- Stock available from M2 to M30; custom wire diameters or extended lengths can be prototyped within 7 days.

Heavy-duty type
For industries, military applications, or machinery with high load requirements, heavy-duty titanium inserts are the perfect choice.
- Exceptional reliability for high-impact areas such as transmission housings, suspension systems, high-speed train seats, and carbon fiber panels.
- Available in lengths from 1D to 4D, with extended and special thread ratio options for thick-wall or multi-layer structures.
- Every batch is tested to ≥ 10 kN pull-out strength and ≥ 350 N·m torque, meeting aerospace and military internal standards, and built to withstand repeated assembly and extreme vibration.

Key-lock type
Equipped with 2 or 4 pre-installed locking keys that automatically expand during installation, these inserts create a mechanical lock with the parent material—maintaining zero displacement even under high-frequency vibration or repeated disassembly.
How to choose the right titanium threaded inserts
Check the base material
Aluminum / magnesium / plastic / injection-molded parts: Choose self-tapping or wire thread inserts for one-step thread reinforcement.
Composites / carbon fiber panels: Choose multi-groove self-tapping types to avoid tapping and protect thin walls.
Check load & vibration
High load + strong vibration (military machinery, suspension systems): Choose heavy-duty key-lock type.
Repair / stripped thread restoration: Choose wire thread inserts to restore original strength in 5 minutes.
Check size & space
Standard M2–M24 / imperial #2-56–1″, with 1D–4D length options.
For confined or ultra-thin wall structures, thin-wall, hex-head, or non-standard custom options are available.
