[0002] Hexagonal bolts refer to fasteners consisting of a head and a screw. Bolts are divided into iron bolts and stainless steel bolts according to their materials. At present, hexagonal bolts are mostly produced by extrusion molding, including the threads on the surface of the screw, which are also extruded by a wire extruder.

[0003] The patent with application number 202021204258.0 discloses a thread processing tool for hexagonal bolts, including a workbench, the four corners of the bottom of the workbench are fixedly connected to support blocks, the center of the top of the workbench is fixedly connected to a placing table, both sides of the top of the workbench are provided with fixing mechanisms, the top of the fixing mechanism is fixedly connected to a box body, the outer side of the inner wall of the box body is fixedly connected to a stepper motor, the output end of the stepper motor is fixedly connected to a threaded rod, the surface of the threaded rod is threadedly connected to a threaded block, the top and bottom of the threaded block are fixedly connected to a movable plate, and an anti-sway mechanism is provided on the side of the movable plate away from the threaded block.

[0004] The thread processing tooling of the external hexagonal bolt achieves the advantage of good fixing effect on the external hexagonal bolt by setting a fixing mechanism, a box body, a stepper motor, a threaded rod, a threaded block, a movable plate, an anti-sway mechanism, a push rod, a clamping block, a buffer pad, a bearing, a box door and a handle that cooperate with each other.
