Explosion venting bolt system

An explosion venting bolt system comprises a screw. A nut is fixedly arranged above the screw. A waterproof gasket is arranged below the nut and sleeves the screw. A lead nut is arranged below the waterproof gasket and arranged on the screw in a matched manner. A traction hole is formed in the lower end of the screw and is a through hole, and the axis of the traction hole and the axis of the screware in intersection and form the included angle. The lead nut is sleeved with a protection cap, the interior of the protection cap is arranged to be in a hexagon nut shape to be matched with the leadnut, a high-strength steel wire is fixedly connected to the inner bottom of the protection cap, and the other end of the high-strength steel wire is connected with the traction wire. In short, secondary damage caused by splashing objects generated during explosion of an explosion venting wall is reduced, and better explosion venting safety performance is provided; and meanwhile, machining and installing are convenient, du
