Din6921 Hex Flange Bolt Flange Bolt
Product Description
The flange bolt is an integrated bolt consisting of a hexagonal head and a flange (a gasket under the hexagon and a hexagonal fixing) and a screw (a cylinder with external threads). Connect the two through-hole parts.
This type of connection is called a bolted connection.If the nut is unscrewed from the bolt, the two parts can be separated again, so the bolt connection is a detachable connection.
Classification:
1. Hexagonal head types: one is flat-brained, the other is concave-brained.
2, surface color categories: according to different needs, the surface has white plating, military green, color yellow, corrosion-resistant Dacromet.
3. Flange type: Depending on the position of the flange bolt, the size requirements of the disc are different. There are also flat bottom and toothed parts.
4. According to the connection force method, there are ordinary and hinged holes. The flange bolts for hinged holes must be matched with the size of the hole and used when receiving lateral force.
In addition, in order to meet the need for locking after installation, there are holes in the rod portion, and these holes can prevent the bolt from loosening when subjected to vibration.
Some flange bolts without threaded polished rod parts are called thin rod flange bolts. Such flange bolts are conducive to the connection of variable forces.
