Welding Bolt, a kind of fastener consisting of head and Screw (cylinder with external thread), needs to be matched with nut to fasten and connect two parts with through hole. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is detachable.

Milling machine with extended top
When milling the spline shaft, we require the full length to be milled once. Because the journals at both ends are too short, the milling cutter cannot be retracted. In the case of single piece production, the one end of the journal is usually lengthened, the full length spline is milled out, the lengthened craft table is removed, and the center hole is re-punched, which is troublesome. To this end, we make long extension shafts that are installed in the spindle hole of the machine (or indexing head). The extended top end is threaded, fitted with a nut, and the top shaft is fitted with a sleeve with 3 tines. When using, install the spline shaft on the front and back of the machine.
