NISSAN 081B7-2251A Hex Flange Bolt

The part with number Nissan 081B7-2251A is a genuine factory (OEM) hex flange bolt (Bolt-Flange). The flanged head functions as an integrated washer, distributing the clamping force resulting from tightening torque across a larger surface area, thereby enhancing fastening stability and preventing loosening in structural assemblies subject to high vibration.

Technical Features and Function

Hex flange bolts are essential fasteners used in assembling the drivetrain, chassis, and other mechanical sub-assemblies. The enlarged bearing surface reduces surface pressure on the fastened component and prevents the bolted joint from relaxing.
