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.
Zinc is by far the most common and economical type of plating for fasteners. The zinc plating adds a protective "sacrificial" top layer against corrosion while also adding a shiny finish to the fastener. Zinc plating is ideal for indoor use where it won't be constantly exposed to harsh elements.
Flange nuts in this seleciton fall under DIN 6923 / ISO 4161 Sizing Standards and are made of Zinc Plated, Class 8 Steel. They are comparable to nuts made of Grade 5 steel.
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.
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.
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.
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.
Zinc plated steel is steel that goes through the process of adding a layer or coating of zinc to protect the steel from corrosion. The added layer of zinc sacrifices itself to keep the steel from rusting, even if the plating is damaged.
No. Zinc plating adds a layer of corrosion resistance for rust protection. Still, it's a thin plating, and it's not as rust resistant as hot-dip galvanizing, which also uses a zinc top layer. While not the most corrosive resistant of materials, zinc plating is easily the most economical and commonly used.
Zinc plating is not a good form of corrosive protection for outdoor use, especially near saltwater or in marine environments. For those applications, stainless steel or potentially hot-dip galvanized steel would work better. Zinc-plated steel is better for indoor use.
