No socket size provided on this website

    No socket size provided on this website, took a chance and bought it assuming it would fit - doesnt fit either of my torque wrenches (1/4 inch and 3/8 inch drives). May be a great piece but this website support is lacking sufficient information re: drive size

    Nice sockets

      Nice addition to the set.
