• For generations sockets with traditional teeth have exerted drive pressure on the six corners of the nut. What, asks Richmond Tools, has been the result?
Millions of damaged, rounded-off nuts, and bruised knuckles.
The Metrinch 6WD socket, it claims, solves this problem. Each one has six shoulders which do not even touch the corners but instead drive off the six walls of the nut. New nuts are therefore not damaged and 6WD will turn old, rounded-off ones more effectively.
All Metrinch 6WD sockets turn both metric and AF nuts, and the majority Whitworth and BSF also. A full Metrinch 6WD socket set is therefore much lighter, simpler to use, more versatile than big, traditional sets, and will fit snugly into even a small tool-box.
The sockets are forged from chrome vanadium steel, and manufactured to exceed the torque requirements of British Standard BS 4006.
