Box wrench

A glasses wrench with a rising angle of 45° × 6°.
[Features]
·Dodecagon (double hexagon).
·Uses a surface contact shape power fit that prevents stress concentration, prevents damage to the corners of the bolt, and contributes to the thinness of the wrench.
·The offset height and length have been reduced, making it easier to use in tight spaces and efficiently transmitting force to bolts and nuts.
·Since the bolt and nut are held at 6 points, it is possible to apply a greater force than a wrench.
·Since the head is ring-shaped, it does not come loose from bolts and nuts, and the load can be applied evenly, enabling stable work.
[Applications]
·A tool for tightening nuts and bolts.
