10.9 Grade DIN912 Internal Hexagon Head Bolt Lengthened Black High Strength

High Strength 10.9 Grade DIN912 Internal Hexagonal Bolt Lengthened Semi-circular Head Internal Hexagonal Screw,Black

Product Description:

The inside hexagon screw head is round on the outside and concave in the middle, and the hexagon screw is the common kind of hexagon screw head. The inner hexagonal screwdriver looks like "7". Cut two ends of the hexagonal steel bar and bend it to 90 degrees to form an inner hexagonal screw wrench.

Internal hexagonal screw is often used in machinery. It has the advantages of easy tightening, disassembly and not easy sliding angle. The inner hexagonal wrench is usually a 90 degree turning, with one end long and one side short. When screwing with the short side, holding the long side of the hand can save a lot of force and tighten the screw well. The long end is divided into a round head (a hexagonal cylinder is similar to a sphere) and a flat head. The round head can be easily inserted into the screw hole for easy disassembly.
