These types of fasteners are produced from high carbon alloy steel , which help them manage with the 150,000 PSI of minimal tensile strength. These fasteners are available in diameters ranging between 3/4′′ and 3/8′′ and lengths up to 31/2′′, measured from the base of the head.
How does a flange nut work?
A flange nut is a nut that has a wide flange at one end. This flange acts as an integrated washer. This serves to distribute the pressure of the nut over the part being secured , reducing the chance of damage to the part and making it less likely to loosen as a result of an uneven fastening surface.
How are flange nuts made?
These nuts are mostly hexagonal in shape and are made up of hardened steel and often coated with zinc . The flange may be serrated to provide a locking action. On a serrated flange nut, the serrations are angled such that they keep the nut from rotating in the direction that would loosen the nut.
Is a flange nut A lock nut?
Flange nuts are hex nuts with a bottom circular flange that is larger than their top hex section. There are two types commonly available: flange lock nuts, which are prevailing torque type lock nuts, and serrated flange nuts, which are free spinning but have a serrated bearing surface to grip the mating surface.
Are flange nuts self locking?
The self locking feature of this flange nut has many advantages in ensuring that the bolt is not damaged. The locknut has a high resistance to temperature and can be used in volatile environments with temperatures ranging between -200°C and 400°C.
Should I use a washer with a flange nut?
On a serrated flange nut, the serrations are angled such that they keep the nut from rotating in the direction that would loosen the nut. Because of the serrations they cannot be used with a washer or on surfaces that must not be scratched. ... Flange nuts (and bolts) are widely used in automobiles and electronic products.
Do flange bolts need washers?
Flanged headed nuts and bolts have been developed to eliminate the deficiencies that have been found with the use of washers. Standard washers are typically softer than the nuts and bolts that they are used with and can often plastically deform under the high compressive stress that they must sustain.
What is a self locking nut?
A Locknut (self-locking nut, locking nut), is a nut which resists loosening through vibration and normal use . This trait makes them essential hardware for a multitutde of applications. Unlike free spinning nuts, lock nuts make use of a deforming elastic or metal material to stay in position against torque and shock.
What is flange coupling?
Flange Couplings are connectors between rotating chutes that have two arrangements of flanges . One of these chutes or flanges is fixed toward the finish of each shaft. To finish the process of transferring power, both the flanges are attached together with numerous nuts and screws.
What does a flange nut look like?
A flange nut looks like a standard hex nut from one side, but the bottom is widened into a circular flange, creating a bell-like shape . Manufacturers serrate the bearing surface of that flange to create serrated flange nuts, allowing for a better grip on the surface of the joint.
What is a serrated flange nut used for?
Serrated flange nuts are hex nuts with non-spinning washers attached at the bottom. Underneath the washers are serrations which allow the nuts to securely fasten when vibrations are present and prevent them from being used with washers or on surfaces that can be scratched.
What is a whiz nut?
The Whiz Lock Nut has serrations on the face of the nut which are used to lock into materials which are softer than the hardness of the nut. The Whiz lock nuts are one piece, all-metal nut and washer self-locking nuts . They simply spin on to mating thread and lock when seated per medium of toothed flange.
What do you call a screw with a flat end?
Machine Screws . A machine screw is a screw or bolt with a flat point. Available in a variety of drive types and heads, they fit a wide variety of applications.
Where does a lock nut washer go?
For the same reason, lock washers always go on the nut side to stop the nut moving . Lock washers are almost always used with a flat washer as well. The nut is also often smaller in profile than the bolt head.
