Description
These thread repair inserts are precision-engineered stainless steel helical inserts designed to restore stripped or damaged internal threads in soft materials like aluminum and magnesium.
Made from corrosion-resistant stainless steel, each thread repair insert offers high tensile strength, excellent elasticity and long service life — ideal for applications requiring repeated assembly/disassembly.
The helical design evenly distributes load across all engaged threads, reduces stress concentration, eliminates pitch error between screw and hole, and absorbs vibration — enhancing fatigue resistance and connection reliability.
Simple installation: drill, tap, and coil-insert using standard tools. No special equipment needed — restores full thread function in damaged holes quickly and cost-effectively.
Package includes 150 pcs total: M3 (30 pcs), M4 (30 pcs), M5 (30 pcs), M6 (30 pcs), M8 (30 pcs). Dimensions: wire diameter 0.8–1.2 mm, coil length 4–10 mm, material: AISI 304 stainless steel, color: natural metallic silver.
This assortment of thread repair insert provides a reliable, reusable solution for repairing worn or stripped internal threads in low-strength base materials such as aluminum, magnesium, plastics or castings. Each stainless steel helicoil-style thread repair insert reinforces the threaded hole, improves load distribution, prevents cross-threading and extends fastener life — especially where frequent disassembly, vibration or high clamping force is involved. Suitable for DIY, automotive, aerospace prototyping, machinery maintenance and industrial repair. Includes only what’s listed: 150 pcs thread repair insert (M3/M4/M5/M6/M8), no tools or accessories.Caractéristiques
