What are flange nuts used for?

Flange nuts have a washer-like base to distribute pressure over a greater surface area and ensure the fastener stay tight. They are commonly used in manufacturing assembly lines where operations are speeded by using a single fastener instead of a nut and washer.

Are flange nuts stronger?

Flange headed nuts and bolts do not suffer from this effect since the washer face is as strong as the bolt/nut itself. It is not unusual for short grip length joints, with several interfaces, to experience a bolt tension reduction of up to 50%.

What are flange bolts?

Used in automotive applications, plumbing, and more, flange bolts feature a washer like flange beneath the bolt head that speeds production time and distributes the clamping load, offering protection to the mating 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 self locking?

This locknut is a one-piece all metal self locking nut that also hosts a captive disc spring washer. The locking feature of this nut is achieved by the two de-pitched self locking slots found on the turret portion if the nut.

Do flange nuts lock?

Flange nuts are available both non-serrated and serrated to provide locking action. The serrations on Serrated Flange Nuts displace material on the mating surface when the nut is wrenched into place, forming a connection which resists loosening.

Are flange nuts locking?

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 grade are flange bolts?

The most common materials for stud bolts (for flanges) are ASTM A193 (grade B7, B8, B8M, B8T), ASTM A453 (grade 660), ASTM A320 (grade L7, L7M), and ASTM A182 (duplex and super duplex bolting). For aggressive fluids and environments, stud bolts can be coated with Xylan, Xylar and other materials.

What is a self-locking nut?

How do you use a flange nut?

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.
