Engine Connection Flange Bolt

Hexagon flange bolts are hex head and flange and screw together form fasteners.


Standard for the Classification of Flange Bolts for Steel Structure Connections

3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 and so on more than 10 grades, of which 8.8

And above the bolt material for low-carbon alloy steel or medium carbon steel and heat treatment (quenching, tempering), commonly known as high-strength bolts, the rest known as ordinary bolts. Bolt performance grade label has two parts of the composition, respectively, said the bolt material nominal tensile strength and yield ratio


Ordinary bolt nail head is very thick, difficult to deformation, after the occurrence of vibration, but also need to re-tighten; flange with a thin part, can be a little deformation, can lock more solid it There is no time to go to the hole when the ordinary bolt no way to use the tool, the flange bolt head smaller, the following flange also play a tightening effect, but can use a special tool to the hole , And hexagonal bolts about the same principle. And then there is the top of the flange pad to use, in the softer, not wearable material safer, will not cause perforation
