20x50 Size Track Bolt For Excavator Sprocket Parts
Track bolts are a type of fastener consisting of a head and a screw (a cylinder with external threads). They need to cooperate with a nut to fasten two parts with through holes. This type of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
