Metric Flange Bolts Hexagonal 8.8 Grade Long Bolts Yellow Zinc
Flange bolts are fully-threaded fasteners with a hexagonal head for use with a wrench or a socket drive. Sometimes called Frame bolts, flange bolts are different from standard bolts as they are designed with a circular flange or a skirt under the head that functions as a built-in washer and distributes the force evenly across the surface to which it will be fastened. The flange helps compensate for excess space in large or misaligned holes yielding increased resistance to rotational loosening.
