Hex flange nuts have a wide flange on one end that acts as an integrated non-spinning washer to spread the pressure of the nut over a larger surface area. These fasteners can also be serrated to create a locking effect, helping them stay tight in vibration-prone applications.Flange lock nuts are reusable, but check for manufacturer recommendations regarding nut reuse, proper lubrication and standard torque values.Flange nuts are a type of fastener that have a wide bottom circular flange that acts as an integrated washer, distributing the load of the nut evenly over a larger surface area. This makes them less likely to damage the surface they are installed against and reduces vibrations that can cause a loosening of the nut. The flange nut's shape also helps to provide stability for the nut, especially on slippery surfaces such as metal and concrete. The flange nut is often used in manufacturing environments where workers are using tools to speed up the assembly process.
Serrated flange nuts are similar to prevailing torque lock nuts in that they use a serrated bearing surface to grip the mating surface. These nuts can be inserted into hex flanges without any friction issues and require less torque to install than their free spinning counterparts. Serrated flange nuts can be used in applications that have softer installation materials such as plastics or rubbers.Prevailing torque lock nuts use a feature that creates interference between the threads of the nut and the mating surface. This causes a resistance to rotation during assembly and disassembly that requires the nut to be wrenched in order to overcome this resistance, known as prevailing torque. This prevents the nut from loosening even if the bolt or screw becomes misaligned with the hex flange. Prevailing torque flange nuts are commonly used in industrial applications such as truck manufacturing equipment.
Hex flange nuts are commonly used with hex flange screws in construction projects that use stainless steel fasteners. They can be used to anchor machinery, pipes and other equipment in areas that are exposed to vibrations and high temperatures. Flange nuts and screws are also commonly used in plumbing projects for connecting faucets, water heaters, washing machines and other appliances to the home's piping system.Stainless steel is an ideal material for hex flange nuts because it is highly durable and corrosion resistant in most environments. SS grade hex flange nuts are produced in many different sizes and can be used with a variety of other stainless steel fasteners such as screws, bolts and washers.In addition to their durability, hex flange nuts are also popular for their ease of installation. The flanged base of these nuts creates an integrated washer that can be used on irregular or oversized holes. This eliminates the need to use a separate washer during installation and can help save time and money on labor costs.
Hex flange nuts are often used in conjunction with hex flange screws because they have the same dimensions and can be easily mated together. A hex flange screw is often used to connect the flange nuts with the hex flange bolts, which provides additional support and strength for the entire fastening system. The hex flange screw can also be used to make repairs to existing installations, making the fastening system more reliable and less likely to loosen over time. This is particularly helpful in projects where the original flange nuts were installed in areas that are susceptible to vibrations or abrasions.
