Rail screw spike, also called sleeper screw, rail screw or lag bolt, is a medium or large metal screw used to fasten a rail tie plates or rail. Rail screw spike is usually made of Q235 steel. Such spikes are always fastened into holes bored into the tie sleeper, sometimes together with imbedded plastic dowels, popularly used for rails with wooden sleepers, especially in America and Canada.

Kingrail uses An automatic production system for spikes is adopted, including an automatic spike feeder, a spike heating machine and a spike rolling machine; the automatic spike feeder includes a spike feeding line, a stepped feeder and a discharge mechanism , the spike feeding line is used to transport the spikes to the stepped feeder, and the stepped feeder sends the spikes to the discharge mechanism by the stepped feeding method; the spike heating machine is located in the automatic feeding of the spikes. The end of the discharging mechanism of the machine includes a turntable feeding mechanism and a heating mechanism. The heating mechanism is arranged on the conveying route of the turntable feeding mechanism to heat the road studs on the turntable feeding mechanism; There is a robot gripper between the feeding mechanisms, and the robot gripper grabs the road stud after passing through the heating mechanism and moves it to the road stud thread rolling machine for thread rolling. The invention realizes the automatic and systematic production of the road stud and improves the production efficiency.
