## Customer Reviews

### ⭐⭐⭐⭐⭐ Work nicely in fiberglass.
*by G***. on April 21, 2025*

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.

### ⭐⭐⭐⭐⭐ inexpensie replacement for the name brand coil
*by D***N on March 21, 2025*
