Hex Flange Bolt

A hexagonal head for use with a wrench. Flange bolts virtually eliminate the need for washers because the area under the bolt head is wider and creates a larger area for even distribution of pressure. Flange bolts that are non-serrated are sometimes called frame bolts. We also supply hex flange nuts that work in tandem with our hex flange bolts. We have different grades of hex flange bolts, hex flange nuts, and hex flange screws to fit a wide range of applications.

▪GRADE 5 HEX FLANGE BOLTS

Hex flange bolts are one-piece head bolts that are flat surfaced. The flange bolts eliminate the need to have a washer since the area under their heads is wide enough to evenly distribute pressure, thus helping to compensate for misaligned holes. Grade 5 hex flange bolts are used in lighter applications.

▪GRADE 8 HEX FLANGE BOLTS

Hex flange bolts are greatly used in areas that are hard to reach since the flage does the work of a washer in distributing pressure. Depend on grade 8 hex flange bolts for use in applications that are demanding.
