DIN 6921 ISO 4162 Hex Flange Bolt are named by the ridge or skirt around the bolt head. A flange bolt is designed to provide the holding power as if a washer was installed, although in some applications they can be employed along with regular bolts paired with washers. It acts as a distributor of the entire clamping load. With their multi-feature function it helps to make jobs easier and faster. ISO 4162 Flange Bolts are regular hex head bolts with built-in washer and externally threaded body. It comes with plain or serrated flange configuration. … Hexagon flange bolts are commonly useful in automotive industry, especially in truck and heavy vehicular frames. ISO 4162 class 8.8 Flange Head Bolt has been developed to eliminate the deficiencies that have been found with the use of washers. There are several reasons as to why flanged nuts and bolts are preferred over standard hexagon fasteners used with washers. ISO 4162 DIN 6921 12 Point Bolt Head are used for a little higher clamp load. It would be seen in the oil and gas industry because of the recessing head of the bolt.

ISO 4162 Class 8.8 Flange Bolt Torque Calculator
Applied Torque, T= (k∙f∙d)/12 in FPS Unit
Where:
- T= Torque in ft-lb
- k= Dimensionless nut factor or tightening factor
- f= axial force in pounds
- d= Nominal bolt dia. in inches
For metric: ===> Torque Applied, T = (k.d.f)/1000
- T = Torque in N-m
- f = Bolt load in N
- d = Bolt diameter in mm
- k=Dimensionless nut factor or tightening factor
