I recommend this tool to all DIY enthusiasts and mechanics. Who has never faced a stubborn screw that eventually break and plunge us into despair ??? I have this tool for several years and could not do without me, he saved the day many times. Exhaust manifold studs stuck broken on cylinder head .... screw, the head ceases to be totally unusable with a wrench or screwdriver .... The principle is simple, the screw being reversed, the 3 jaws will gradually tighten the screw / bolt in the direction of loosening it, offering optimum support. Very good quality for this tool brand LASER (English brand) / quality ratio perfect price.
