Metrinch

A nut or a bolt has flats and corners. The corners are more easily damaged and do not offer the optimum grip for a tool.The Metrinch Tool aimed to design sockets and spanners, which would not only have longer effective life, but also ensures minimal damage to the fasteners on which they are used.The dimensions of Metrinch sockets and spanners have been precisely calculated, so that a single Metrinch tool operates on Metric, SAE and other Inch systems.Each tool is made of drop-forged high-quality Chrome Vanadium Alloy Steel. The manufacturer is so confident that you will be satisfied with your experience that they backed each piece with a lifetime replacement guarantee if it should ever break.
