Frequently Asked Questions (FAQs)
1. What are hex flange nuts for?
Hex Nuts with Integrated Washers Flange nuts are used to spread the load placed on the nut over a wider surface area to prevent damage to the installation material. The flange acts as a washer, which allows the nut to fasten evenly to the installation material's surface.
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.
