Classification and use of Flange Bolts

Flange Bolts consisting of hexagonal head and Flange (hexagonal below the gasket and hexagonal fixed one) and screw (with external thread cylinder) two parts of the integration of the Bolts, to be matched with the nut, a part used to fasten and connect two through holes.

Flange Bolts classification

1.hexagonal head type: one is flat brain, the other is concave brain.

2.surface color categories: according to different needs, the surface has a white, green, yellow, corrosion-resistant DACROMET.

3.Flange type: according to the Flange Bolts of the use of different locations, the size of the disc requirements are different, and another flat bottom and teeth of the points, teeth with anti-skid role.

4.According to the force mode of connection: There are ordinary and reamed holes. Flange Bolts for reaming holes shall match the size of the hole and shall be used when subjected to transverse forces.

In addition, in order to meet the need of locking after installation, there are holes in the rod, which can prevent the bolt from loosening when it is subjected to vibration. Some Flange Bolts are called thin-rod Flange Bolts. The Flange Bolts facilitate the connection of variable forces.

Use of flange bolts

Flange bolts are composed of hexagonal head and flange plate, its“Support area and stress area ratio” is larger than ordinary bolts, so this bolt can withstand higher pre-tightening force, anti-looseness performance is better, so it is widely used in automobile engine, heavy machinery and other products.
