The internal hexagonal wrench is an L-shaped hexagonal steel bar, specially used for tightening internal hexagonal cylindrical head screws, commonly 1.5-10 mm, made of chrome vanadium steel or S2 tool steel and quenched as a whole. Selection criteria: The size must correspond to the screw (half a size difference must have a sliding angle), whether it has a ball head (the ball head can be twisted diagonally at 20 ° -30 °, and is easy to use in blind spots), whether it has anti demagnetization, and whether the hardness of the chrome vanadium steel is marked with HRC 60+.
