A hex flange nut is a hex-headed fastener that has a flat-like flange built into it. This flange distributes pressure from the tightened nut over a larger area, making it less likely to loosen due to vibration. In addition, it eliminates the need to put a washer between the nut and the surface being fastened. This saves time and money during installation. However, there are a few things to keep in mind when using this type of fastener.
Hex flange nuts come with a serrated or non-serrated flange, which can help increase the locking strength of the nut. The serrations on the flange are angled to bite into the surface being fastened and displaced material, helping lock the nut in place and prevent it from backing off during use.
Non-serrated hex flange nuts do not provide this locking effect, but they have the advantage of eliminating the need for a washer in installations. The flanged portion of the nut also helps to reduce the chances of the nut threads damaging the mating surfaces.
These nuts are ideal for applications that require a strong clamping force or where the screw joints are subject to vibration. They are commonly used in furniture, machinery, and other industrial applications. They can be used on a variety of fasteners, including screws and bolts.
The hex-shaped head of the flange nut allows for easy use with wrenches and ratchets. The flange also protects the threads from damage, allowing them to last longer. Hex flange nuts are available in several sizes and materials, including stainless steel. In addition, they can be found with a variety of coatings, including zinc and chrome.
While hex flange nuts can be used for a wide range of applications, they are especially useful in environments with high temperatures or corrosive materials. They are often coated with a layer of zinc, which helps prevent corrosion in harsh conditions. In addition, these nuts are a great choice for applications that involve lubricants or other chemicals.
Hex flange nuts look like standard hex nuts, but they have a widened bottom that resembles a washer. The flange spreads out and creates a bell shape. This gives hex flange nuts more surface area to distribute the nut's tightening pressure over a larger area, preventing loosening from vibrations or impact forces. Because of this, hex flange nuts are often used in commercial and industrial settings, such as for lawn and garden equipment, furniture, and truck manufacturing. While flange nuts are useful for most applications, it's important to follow the manufacturer's recommendations regarding nut reuse, thread lubricants, and torque values. If the prevailing torque value is too low, the joint may not be tightened to the correct clamping force. For this reason, it's best to only use flange nuts for a limited number of times.
