Description

A flange bolt is a fastener with a circular flange or skirt that extends from the head of the bolt. The flange distributes force across a larger surface area, which helps to secure the joint. Flange bolts are often used to connect two flanges, which are flat, disc-like components with pre-drilled holes. Uses Secure joints Flange bolts can be used to secure joints in vehicles, such as the transmission to the engine. Create a leak-proof seal Flange bolts can be used to create a leak-proof seal between flanges, which can contain gases, liquids, or other substances. Increase load-bearing capacity Flange bolts can be used to increase the load-bearing capacity of a structure. Features Flange bolts can be made from a variety of materials, including stainless steel, carbon steel, and alloy steel. Flange bolts can be tightened or loosened with a standard hex wrench or socket. Flange bolts have a hexagonal head and a threaded shank. Flange bolts have an integral washer-like flange beneath the head. Related terms Non-serrated flange bolts are sometimes called frame bolts. Flange nuts are defined by standards such as ASME B18.2.2, ISO 4161, and DIN EN 1661.
