Hex Serrated Flange Nuts in A2 Stainless Steel
Metric Hex Nuts with Serrated Integrated Washers
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. The flange acts as a washer, which allows the nut to fasten evenly to the installation material's surface.
Hex flange nuts are very common and used widely in softer installation materials. These nuts come with a serrated flange. These flange nuts come with serrations on the flange's bottom to create a locking effect. The serrations bite into the material installed, making the nut less likely to loosen over time due to vibrations. Hex flange nuts also save time and money by removing the need for a washer added to each fastener assembly during installation.
The A2 grade of Stainless steel is suitable for many general purpose applications, especially freshwater and non-salt water wet environments. Corrosion-resistant and durable, A2 stainless steel is equivalent to the 18-8 or 304 grade of stainless steel.

What is a serrated flange nut?
Serrated flange nuts are hex nuts with built-in non-spinning washers with serrations on the bottom. This kind of flange nut is used to help prevent loosening when vibrations are present.
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 stainless steel good for?
Stainless steel is good for general purpose applications, especially those involving water or freshwater. Suppose you need stainless steel for more corrosive environments, such as marine or salt-water applications. In that case, we recommend the 316 grade of stainless steel.
Can I use stainless steel nuts with bolts of a different metal?
Depends on the material. Some materials, such as zinc plated steel, are safe to mix with stainless steel. However, aluminum is not safe to use because it risks galvanic corrosion of the materials. We recommend keeping like-metals together in applications.
