Flange Nuts Details

A flange nut is a nut that has a wide flange at one end that acts as an integrated washer. This serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface. These nuts are mostly hexagonal in shape and are made up of hardened steel and often coated with zinc.
Flange nuts (and bolts) are widely used in automobiles and electronic products.

Hex Flange Nuts are hex nuts with a wide flanged portion near one end that acts as an integrated non-spinning washer. Flange nuts are used to spread the load placed on the nut over a wider surface area to prevent damage to the installation material. They can come in serrated flange nuts or non-serrated styles.

Flange nuts come in a variety of diameters and lengths. We carry them in coarse and fine thread. Listed below are the diameters we carry:

  • Stainless steel – SS302, SS304, SS316, (good tenacity),Stainless steel A2 A4

  • Brass – C36000 ( C26800), C37700 ( HPb59), C38500( HPb58),C27200CuZn37), C28000(CuZn40)
  • Bronze–C51000, C52100, C54400, etc
  • Aluminum – Al6061, Al6063 etc
  • Carbon steel – C1006,C1010,C1018,C1022,C1035K,C1045

  • Thread Type:Machine screws,bolts, self tapping etc

Application

Flange nuts are often used in fastening applications involving oversized holes. They have a protruding rim that covers more surface area. Even if the hole is too big for a traditional nut, it may support the use of a flanged nut.

Also, our custom fastener, bolts, screws are widely used in the below industries

  • Electronics
  • Petrochemicals
  • Consumer products
  • Transportation
  • Agriculture
  • Heavy machinery
  • Construction
  • Automotive
  • Medical
  • Military
  • Aerospace
  • Oil and gas

Frequently Asked Questions

 The integrated washer of a flange nut works in the same way as a standard washer, providing a greater area to distribute the nut’s pressure over the part being secured. If the flange has serrations, these serrations bite into the material installed, making the nut less likely to loosen over time due to vibrations.

The flange on a flanged nut will turn with the nut whereas a washer often will not. The washer, due to its resistance to turning, thus helps to control wear at the mating surfaces. In effect, a washer will protect a surface more than a flanged nut. This can be huge if locking washers are also being used on the joint.

Because of the serrations, they cannot be used with a washer or on surfaces that must not be scratched. The serrations help in preventing the vibration of the nut from moving the fastener, thus maintaining the holding power of the nut.

Using a hex nut and washer instead of a flange nut introduces an additional inner interface and the associated additional preload loss due to embedding and relaxation in that interface.

The flange acts as a washer, which allows the nut to fasten evenly to the installation material’s surface. … The serrations bite into the material installed, making the nut less likely to loosen over time due to vibrations.
