Tangless Wire Thread Insert – Precision Engineered for Critical Applications

AVIC Flight’s Tangless Wire Thread Insert is a helically coiled, high-performance fastening solution engineered to create permanent, wear-resistant internal threads in soft, brittle, or damaged parent materials. Unlike traditional tanged inserts, its tang-free design eliminates FOD (Foreign Object Debris) risks and streamlines installation—critical for industries where precision and reliability are non-negotiable. Crafted from cold-rolled rhombic stainless steel wire, it forms a concentric body of high-precision internal and external threads that exceed the strength of most base materia

    Why Choose Our Self-Tapping Inserts?

    Tanged wire thread inserts require tedious tang break-off, retrieval, and post-installation gauge checks—steps that waste production time and create FOD risks. A single misplaced tang can damage sensitive equipment (e.g., engines, circuit boards) or force costly rework. For maintenance teams, removing tanged inserts often damages parent threads, increasing repair costs

    Our Tangless Solution: 4 Key Fixes

    1. No FOD, No Failures

    By removing the tang entirely, we eliminate the risk of metal debris contaminating your systems. Critical for aerospace, medical, and electronics applications where even tiny particles cause downtime .

    2. 40% Faster Installation

    Skip tang break-off and cleanup. Our bi-directional design lets you insert from either end, and paired with dedicated power tools, you can complete installations with a single button press .

    3. Damage-Free Removal

    Special tools enable quick extraction without harming parent threads or the insert itself—perfect for maintenance and repair of expensive machinery .

    4. Long-Lasting Thread Reinforcement

    The coiled stainless steel design reinforces weak or worn threads, extending component lifespan by 3–5x compared to direct tapping. Resists vibration-induced loosening and corrosion .

    Real-World Results

    Automotive Plant: Reduced transmission assembly time by 35 minutes per unit after switching from tanged inserts.

    Aerospace MRO:. Eliminated 2 FOD-related engine repairs monthly, saving $40k+ in downtime costs

    Machine Shop: Cut maintenance time for lathe thread repairs by 60% with damage-free insert removal.
