Serrated M18 Galvanized Grade 4 Hex Flange Nuts ISO 4161

FAQs

• 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.
• How do you tighten a locking flange nut?
• Like any other hex nut, you can tighten a locking flange nut with a wrench or ratchet of the appropriate size after threading it onto the end of the bolt you're installing.
• How do you measure a flange nut?
• Flange nuts are measured based on their internal threading, displayed as Diameter - Thread Pitch. To find a matching bolt for the nut, or vice versa, this thread size needs to match. For example, a 1/4"-20 flange nut can only be fastened onto a 1/4"-20 bolt or thread.
• What is a hex flange nut?
• 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 or non-serrated styles.
• What does a flange nut look like?
• A flange nut looks like a standard hex nut but with a widened bottom resembling a washer that's integrated with the nut. This gives flange nuts a slight bell shape to them.
