Flange Nuts

A flange nut is a hex nut with an extended circular base spreading out from the bottom of the nut, acting as an integrated, non-spinning washer. Flange nuts are used to speed up assembly operations or in applications where their large bearing surface can cover big holes / slots. Raptor Supplies offers these flange nuts from brands like Accurate Mfd Products, AME, Disco, Fabory, Te-Co and Lisle.

Features

  • Also known as collar nuts, flange nuts have applications in automotive assembly and manufacturing processes.
  • The locking characteristic prevents these nuts from loosening until seated, permitting them to work as stop nuts / spacers for rotating components.
  • These flange nuts distribute pressure across a large surface area.
  • They feature a wide base that eliminates the need for a separate washer.
  • They feature a unique design that compensates for the minor misalignment of the clamp to offer accurate clamping force.
  • Assemblies include a spherical washer and flange nut.
  • Te-Co spherical nuts feature a unique design that compensates for the minor misalignment of the clamp to offer accurate clamping force.
  • Assemblies include a spherical washer and flange nut.

Frequently Asked Questions

What standards do flange nuts comply with?

These flange nuts comply with DIN (German Institute for Standardisation), ISO (International Organization for Standardisation), JIS (Japanese Industrial Standards), NAS (National Aerospace Standards) and military standards.

What is a hex flange nut?

Hex flange nuts are hex nuts with a broad flanged portion near one end to serve as a built-in, non-spinning washer. Flange nuts spread the load placed on the nut over a broad surface area to prevent the deterioration of the installation material.

How to tighten a locking flange nut?

A flange nut can be tightened with a wrench or ratchet (of suitable size) after threading it onto the end of the bolt being installed.

How do flange nuts operate?

The in-built washer of flange nuts operates in the same way as a standard washer, offering a larger area to disperse the nut's pressure over the part being secured. Selected flanges come with serrations that bite into the material, making them less prone to loosening over time due to vibrations.
