Bolt: Mechanical parts, cylindrical threaded fasteners with nuts. A type of fastener consisting of a head and a screw (a cylinder with an external thread) is required to be fitted with a nut for fastening the 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 ***achable connection.
BKNFX-11 bolt eddy current sorter and automatic screw sorter are suitable for high-strength bolt heat treatment state, crack, wrong thread anchor, and mixture sorting.
The shape of bolt:
Generally, the countersunk head is used where the surface is smooth and does not protrude after the connection is required because the countersunk head can be screwed into the part. The round head can also be screwed into the part. The tightening force of the square head can be larger, but the size is large. In addition, in order to meet the needs of locking after installation, there are holes in the head and holes in the rods, which can not loosen the bolt when it is vibrated. Some bolts without threads are to be thin, called thin waist bolts. This type of bolt facilitates the coupling of the force. There are special high-strength bolts on the steel structure, the head will be larger and the size will change. |
