Is the rod diameter of the long screws for plug sockets?

Screws in excess of 100mm and grooved hexagonal socket screws are collectively referred to as long screws for plug sockets. Screws over 100mm are generally half-threaded and do not require full threads, which only increase the cost and difficulty of production.

The diameter of the long screws for plug sockets is divided into big rod and small rod. If the rod diameter is larger than the thread diameter, this is the long screw of the big rod, need to open die production, the cost increases. If the diameter of the rod is less than the diameter of the thread, this is the long screw of the small rod, and the diameter of the rod is the diameter of the wire, which reduces the weight of the screw, reduces the die and reduces the cost.
