Serrated Flange Bolts

Hex Head Serrated Flange Bolts

Serrated flange bolts Armed 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. The flange may be serrated to provide a locking action, Moreover, 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.
