Flange bolts feature a built in washer under the bolt head that helps to distribute the clamping load over a larger area. This "one-piece" design eliminates the need of a separate washer under the bolt head and is preferable for some applications as it can be more efficient and easier to use. A washer is still needed on the nut side unless using a flange nut. The serrations under the flange bite into the surface and help to resist loosening due to vibration.

  • Size: 1/4 inch-20 X 3 inch
  • Hex bolt with a serrated circular flange under the head
  • Flange eliminates need for separate washer
  • Serrations bite into surface and can help to prevent loosening

  • Thread Type: Coarse, Thread Class: UNC-2A, Point Style: Blunt
  • Specification(s) Met: ASME B18.2.1, ASME B18.6.3, and ASME B1.1
