M8 X 25 Carbon Steel Hex Head Flange Bolt Customized Left Thread /
Right Thread
Description:
Hexagon flange bolt and the flange (hex washer and hex fixed below one) and the screw (externally threaded cylinder) bolt integral two-part, need to cooperate with the nut, for tightening connecting the two through-hole parts.
There are two hex flange types: hexagonal head, there are two, one is the flat head, the other is concave.
The surface color categories: according to different needs, the surface coating of white, green, yellow color, and the other never rust dacromet.
Flange categories: Depending on the point of use flange bolts, disk size requirements are different, otherwise flat and toothed points, toothed anti-slip effect.
As the force of connecting, there are common and the other have articulation hole of the flange bolts articulation hole to hole size and fit that is used when lateral force.
In addition, to meet the needs of the lock after installation, the rod portion with a hole, the holes can not screw loose when subject to vibration.
Some flange bolts not threaded rod to be meticulous, called the shank flange bolt. This is conducive to the flange bolts by variable force coupling.
There are special high strength bolts on steel. The head will become bigger and more dimensions have changed.
