100PCS M6 x1‑1.5D Thread Repair Insert, 304 Stainless Steel

These 304 stainless steel wire thread inserts are designed for threaded repair and reinforcement in low-strength materials. They help improve wear resistance at bolt connections, reduce thread damage, and support a more even load distribution on the threads. The elastic structure can help absorb vibration and improve connection strength, while the locking design helps keep screws from loosening under shock or vibration. With higher hardness than the screw itself, the insert is made for repeated use and reliable connection performance.Material: 304 Stainless SteelInner Diameter: 6 mm (0.24 in)Thread Pitch: 1.5 mm (0.06 in)Length: 9 mm (0.35 in)Color: SilverPackage Includes: 100 x Wire Screw Sleeve
