Used them to repair a few stripped threads on my truck's skid plate, and the 304 stainless steel held up perfectly under the torque. The 50-count pack gave me plenty of spares, and the helical coils threaded in cleanly without any binding.

Had to rethread a few stripped holes on a steel bracket, and these inserts cut clean threads without any binding or deformation. The stainless material feels solid and the internal threads held up through multiple test fits before final installation.

Installed a dozen of these on an aluminum engine block and they're holding up well. The 304 stainless gives me confidence it won't corrode, and the 50-pack covered my whole job with spares to spare.
