Tangless Wire Inserts: Zero-Installation-Waste Thread Repair for Metals, Plastics & Ceramics
Tangless wire thread inserts revolutionize thread reinforcement with their tailless design that eliminates post-installation cleanup. Manufactured from cold-rolled 304/316 stainless steel, they create permanent high-strength threads in soft alloys, polymers, and even brittle substrates like ceramics. The patented coil geometry provides 300% higher pullout resistance than native threads while preventing stripping in low-strength materials.
Breakthrough Technical Advantages
► CROSS-MATERIAL PERFORMANCE:
1. No Tang Removal丨Direct assembly after installation丨**30% faster workflow**丨ISO 14399
2. Diamond-Shaped Wire Profile丨4-point contact with parent material丨**Vibration resistance +400%**
3. Full-Perimeter Engagement丨360° load distribution丨**No weak axis**
4. Cryo-Treated Stainless Steel丨HRC 42-46 hardness丨**Salt fog 5000+hrs**

Installation vs. Traditional Inserts
☆ TRADITIONAL:
Drill → Tap → Install → Break tang → Remove debris → Assemble
☆ TANGLESS:
Drill → Tap → Install → *IMMEDIATE ASSEMBLY*
*Saves 78 seconds per insert (MIL-STD-1312 time study)*
Technical Validation:
☆ 25 kN shear strength (M8 size per ISO 898-1)
☆ 10 million+ vibration cycles (MIL-STD-167-1)
☆ -200°C to 650°C thermal cycling (ASTM E831)
