The new type bolt comprises a screw rod, the upper end of the screw rod is fixedly connected with a flat washer, the upper end surface of the flat washer is fixedly connected with a flange head, the upper end surface of the flange head is provided with a cross groove, and the lower end of the flat washer is provided with a cross groove. A gasket is attached to the connection. This new type of bolt, through the set cross groove and flange head, can use a cross head screwdriver or wrench to tighten or loosen the bolt, and the cross groove completely penetrates the flange head, the flat washer and the screw rod. Therefore, when the bolt is broken, the bolt can still be quickly disassembled by a cross-head screwdriver, and the flat washer provided can increase the contact area between the bolt and the object to be connected, so that the flange head can be dispersed. The pressure of the object to be connected, and the anti-skid teeth on the lower end surface of the gasket can be embedded in the object to be connected to prevent the gasket from rotating, so friction will occur between the flat gasket of the bolt and the gasket, so that there will be no sudden change in torque. , easy to use.
