Frequently Asked Questions (FAQs)

1. What is a flange nut used for?

Flange nuts are commonly used to speed up assembly operations or in areas where their larger bearing surface can cover oversized holes or slots The additional bearing surface also serves to distribute the pressure of the nut over the part being secured, reducing the chance of damage or to loosen.

2. Are flange nuts stronger?

Flange lock nuts provide more space for serration. Serration is the process of putting irregular surface to increase the resistance force between the surfaces. As there is more mating space, it provides more tightening strength.

3. Are flange nuts reusable?

Flange lock nuts are reusable but only for a limited number of times because the prevailing torque declines each time the nut is used. Always follow the manufacturer's recommendations regarding nut reuse, thread lubricants and torque values.
