Metrinch Spanner

Manufactured from chrome vanadium steel with a bright chrome finish at the ends. The jaw and ring are designed to grip the flats of the hexagon, not the corners which enables one spanner to fit metric and imperial A/F, Whitworth and BS/BSF.,This makes tool selection easier and fewer spanners to carry. The nature of the jaw design on these spanners makes them ideal for turning old worn, rounded hexagons and protecting new ones.
