This pack of 40 M10 x 1.5mm x 3D Helicoil wire thread inserts is crafted from premium 304 stainless steel, offering corrosion resistance and exceptional durability. Designed for precision fit and anti-loose performance, these inserts enhance thread strength and vibration resistance, making them essential for high-stress applications in aerospace and industrial settings.

Works great
The former owner of my 2009 Nissan Versa had welded the oxygen sensor in. After removing the old sensor and welding, I used the helicoil to replace the thread. It was easy to insert the product and to put the new sensor in.

Work nicely in fiberglass.
These worked very nicely to add machine thread holes to fiberglass on my boat. I was tired of repairing holes where wood screws directly into fiberglass stripped out or left stress cracks. This also works better than a wood screw in thicker fiberglass where wood screws tend to bind and snap off. The other benefit is that wood screw threads cutting into gelcoat tend to create stress points that start stress cracks in the gelcoat that radiate out from the screws. Using a helicoil with a machine thread screw seems to eliminate that problem. It is important to use an anticorrosion compound like Tef-Gel in the marine environment since, while these helicoils are stainless steel, they are not a marine-grade alloy.

Saved a few parts from the trash
Used these M3×0.5 (1D) coils to fix stripped threads on an aluminum bracket and a 3D-printer part. The coils are consistent, no burrs, and standard M3 screws run in smooth with zero wobble. Tangs snapped cleanly with a punch. Once installed, the threads feel stronger than the originals.Tips: you’ll need the proper M3×0.5 STI tap and about a 3.2 mm drill. A dab of blue Loctite on the outside of the coil keeps it put. 1D length is perfect for shallow holes; if you need more engagement, look for 1.5D/2D.
