Excelente producto, lo utilizé para sacar un tornillo de un Cuerpo de Aceleración de un Nissan Tsuru y cumplió a cabalidad con el objetivo, los dientes filosos en espiral, mordieron perfectamente la cabeza del tornillo y lo desenrroscaron muy bien y problema resuelto. GRACIAS AMAZON.

Tool worked great. I had tried to remove this 15mm bolt several times with a 6 sided socket and socket wrench, socket and 12 inch breaker bar with heat. The bolt was soft and rounding off. Impact wrench and socket rounded it off completely. I drove the 14mm socket from this set onto the rounded 15mm, added some heat, and used a 3 foot cheater bar. The bolt broke free with tremendous pressure applied. It was hard to believe the bolt head didn’t shear. The socket was still in perfect condition. That was the first and only time I’ve used a socket like this. The cost of the set was worth every penny for just that one bolt to me.
