Flange Fasteners-Flange Screws, Bolts, Nuts, Washers

Flange Screws & Flange Bolts feature by the ridge of the bolt head. The bolt’s circular flange under the head acts like a washer to distribute the load and is designed to provide the same holding power as a washer. They are many types of flange screws and bolts

  • Serrated flange screws bolts: with teeth-like serrations, serrated flange bolts are one-piece bolts that bite into surfaces to resist vibration. This bolt is identifiable by the ridge or surrounding the bolt head, this built-in washer under the head of the Bolt acts to distribute the clamping load over a greater area. Also, the serration help in preventing the vibration of the nut from moving the fastener, thus maintaining the holding power of the nut. Hexagon nuts with flange and serration are mostly used in joining wood and plastic.
  • Indented hex flange screws can be used as an option to a more costly trimmed hex head screw. They are available as thread forming, thread-cutting, and machine screw threads.
  • Indented Hex Flange Lag Screws: This hex cap style screw is a one-piece hex-washer head screw with a flat bearing surface, spaced threads, and a gimlet point. Some manufacturers prefer hex flange bolts over traditional lag screws because they do not require flat washers.  stainless steel or The galvanized finish offers increased resistance to corrosion.

Flange Washers are washers with a raised inside diameter with a flange base. This allows them to be used in applications where a large bearing surface is needed but the material it is resting on is soft and can be damaged easily

Flange Nuts look like a standard hex nut from one side, but the bottom is widened into a circular flange, creating a bell-like shape. Manufacturers serrate the bearing surface of that flange to create serrated flange nuts, allowing for a better grip on the surface of the joint. Flange nuts are commonly used to speed up assembly operations or in areas where their larger bearing surface can cover oversized holes or slots The additional bearing surface also serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage or to loosen. There are two types of flange nuts flange lock nuts, which are prevailing torque type lock nuts, and serrated flange nuts, which are free spinning but have a serrated bearing surface to grip the mating surface
