DIN6921 High strength grade 8.8/10.9/12.9 black hexagon flange bolt

Description:

Flange by hexagon head bolts and flange (hexagon gaskets and hexagonal fixed one below) and screw (cylinder) with external thread of the integration of the two parts of bolt, nut to cooperate, two hole is used for fastening parts.Flange bolts have a circular flange under the head that acts looks like a washer to distribute the load. Flange bolts that are non-serrated are sometimes so it also called frame bolts.

3, flange type: according to the use of flange bolt location is different, the size of the tray for each are not identical, otherwise flat or toothed, toothed non-slip effect.
4, according to the connection of loading mode, have common and articulation hole. Articulation hole with flange bolts should cooperate and the size of the hole, when used in the lateral force.
In addition to meet the needs of the lock after installation, valve stem hole, the hole can make not loose bolts by vibration.
Some flange bolt not polished rod part of the thread to do, call thin rod flange bolts. This kind of flange bolt is conducive to the force of the connection.

These bolts are also called Frame bolts. A hex head for use with a wrench.
