Product description

(1)What is a hex flange nut?
Hex Flange Nuts are hex nuts with a wide flange 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 or non-serrated styles.
(2)Do you need lock washer with flange nut?
The flange on a flange 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 flange nut. This can be huge if locking washers are also being used on the joint.
(3)How does a flange nut work?
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.
